7 Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow.   8 Make me to hear joy and gladness; that the bones which thou hast broken may rejoice.   9 Hide thy face from my sins, and blot out all mine iniquities.   10 Create in me a clean heart, O God; and renew a right spirit within me.   11 Cast me not away from thy presence; and take not thy holy spirit from me.   12 Restore unto me the joy of thy salvation; and uphold me with thy free spirit.   13 Then will I teach transgressors thy ways; and sinners shall be converted unto thee.

      I. See here what David prays for. Many excellent petitions he here puts up, to which if we do but add, "for Christ's sake," they are as evangelical as any other.

      1. He prays that God would cleanse him from his sins and the defilement he had contracted by them (v. 7): "Purge me with hyssop; that is, pardon my sins, and let me know that they are pardoned, that I may be restored to those privileges which by sin I have forfeited and lost." The expression here alludes to a ceremonial distinction, that of cleansing the leper, or those that were unclean by the touch of a body by sprinkling water, or blood, or both upon them with a bunch of hyssop, by which they were, at length, discharged from the restraints they were laid under by their pollution. "Lord, let me be as well assured of my restoration to thy favour, and to the privilege of communion with thee, as they were thereby assured of their re-admission to their former privileges." But it is founded upon gospel-grace: Purge me with hyssop, that is, with the blood of Christ applied to my soul by a lively faith, as water of purification was sprinkled with a bunch of hyssop. It is the blood of Christ (which is therefore called the blood of sprinkling, Heb. xii. 24), that purges the conscience from dead works, from that guilt of sin and dread of God which shut us out of communion with him, as the touch of a dead body, under the law, shut a man out from the courts of God's house. If this blood of Christ, which cleanses from all sin, cleanse us from our sin, then we shall be clean indeed, Heb. x. 2. If we be washed in this fountain opened, we shall be whiter than snow, not only acquitted but accepted; so those are that are justified. Isa. i. 18, Though your sins have been as scarlet, they shall be white as snow.

      2. He prays that, his sins being pardoned, he might have the comfort of that pardon. He asks not to be comforted till first he is cleansed; but if sin, the bitter root of sorrow, be taken away, he can pray in faith, "Make me to hear joy and gladness (v. 8), that is, let me have a well-grounded peace, of thy creating, thy speaking, so that the bones which thou hast broken by convictions and threatenings may rejoice, may not only be set again, and eased from the pain, but may be sensibly comforted, and, as the prophet speaks, may flourish as a herb." Note, (1.) The pain of a heart truly broken for sin may well be compared to that of a broken bone; and it is the same Spirit who as a Spirit of bondage smites and wounds and as a Spirit of adoption heals and binds up. (2.) The comfort and joy that arise from a sealed pardon to a penitent sinner are as refreshing as perfect ease from the most exquisite pain. (3.) It is God's work, not only to speak this joy and gladness, but to make us hear it and take the comfort of it. He earnestly desires that God would lift up the light of his countenance upon him, and so put gladness into his heart, that he would not only be reconciled to him, but, which is a further act of grace, let him know that he was so.

      3. He prays for a complete and effectual pardon. This is that which he is most earnest for as the foundation of his comfort (v. 9): "Hide thy face from my sins, that is, be not provoked by them to deal with me as I deserve; they are ever before me, let them be cast behind thy back. Blot out all my iniquities out of the book of thy account; blot them out, as a cloud is blotted out and dispelled by the beams of the sun," Isa. xliv. 22.

      4. He prays for sanctifying grace; and this every true penitent is as earnest for as for pardon and peace, v. 10. He does not pray, "Lord, preserve me my reputation," as Saul, I have sinned, yet honour me before this people. No; his great concern is to get his corrupt nature changed: the sin he had been guilty of was, (1.) An evidence of its impurity, and therefore he prays, Create in me a clean heart, O God! He now saw, more than ever, what an unclean heart he had, and sadly laments it, but sees it is not in his own power to amend it, and therefore begs of God (whose prerogative it is to create) that he would create in him a clean heart. He only that made the heart can new-make it; and to his power nothing is impossible. He created the world by the word of his power as the God of nature, and it is by the word of his power as the God of grace that we are clean (John xv. 3), that we are sanctified, John xvii. 17. (2.) It was the cause of its disorder, and undid much of the good work that had been wrought in him; and therefore he prays, "Lord, renew a right spirit within me; repair the decays of spiritual strength which this sin has been the cause of, and set me to rights again." Renew a constant spirit within me, so some. He had, in this matter, discovered much inconstancy and inconsistency with himself, and therefore he prays, "Lord, fix me for the time to come, that I may never in like manner depart from thee."

      5. He prays for the continuance of God's good-will towards him and the progress of his good work in him, v. 11. (1.) That he might never be shut out from God's favour: "Cast me not away from thy presence, as one whom thou abhorrest and canst not endure to look upon." He prays that he might not be thrown out of God's protection, but that wherever he went, he might have the divine presence with him, might be under the guidance of his wisdom and in the custody of his power, and that he might not be forbidden communion with God: "Let me not be banished thy courts, but always have liberty of access to thee by prayer." He does not deprecate the temporal judgments which God by Nathan had threatened to bring upon him. "God's will be done; but, Lord, rebuke me no in thy wrath. If the sword come into my house never to depart from it, yet let me have a God to go to in my distresses, and all shall be well." (2.) That he might never be deprived of God's grace: Take not thy Holy Spirit from me. He knew he had by his sin grieved the Spirit and provoked him to with draw, and that because he also was flesh God might justly have said that his Spirit should no more strive with him nor work upon him, Gen. vi. 3. This he dreads more than any thing. We are undone if God take his Holy Spirit from us. Saul was a sad instance of this. How exceedingly sinful, how exceedingly miserable, was he, when the Spirit of the Lord had departed from him! David knew it, and therefore begs thus earnestly: "Lord, whatever thou take from me, my children, my crown, my life, yet take not thy Holy Spirit from me" (see 2 Sam. vii. 15), "but continue thy Holy Spirit with me, to perfect the work of my repentance, to prevent my relapse into sin, and to enable me to discharge my duty both as a prince and as a psalmist."

      6. He prays for the restoration of divine comforts and the perpetual communications of divine grace, v. 12. David finds two ill effects of his sin:-- (1.) It had made him sad, and therefore he prays, Restore unto me the joy of thy salvation. A child of God knows no true nor solid joy but the joy of God's salvation, joy in God his Saviour and in the hope of eternal life. By wilful sin we forfeit this joy and deprive ourselves of it; our evidences cannot but be clouded and our hopes shaken. When we give ourselves so much cause to doubt of our interest in the salvation, how can we expect the joy of it? But, when we truly repent, we may pray and hope that God will restore to us those joys. Those that sow in penitential tears shall reap in the joys of God's salvation when the times of refreshing shall come. (2.) It had made him weak, and therefore he prays, "Uphold me with the free Spirit: I am ready to fall, either into sin or into despair; Lord, sustain me; my own spirit" (though the spirit of a man will go far towards the sustaining of his infirmity) "is not sufficient; if I be left to myself, I shall certainly sink; therefore uphold me with thy Spirit, let him counterwork the evil spirit that would cast me down from my excellency. Thy Spirit is a free spirit, a free gent himself, working freely" (and that makes those free whom he works upon, for where the Spirit of the Lord is there is liberty)--"thy ingenuous princely Spirit." He was conscious to himself of having acted, in the matter of Uriah, very disingenuously and unlike a prince; his behaviour was base and paltry: "Lord," says he, "let thy Spirit inspire my soul with noble and generous principles, that I may always act as becomes me." A free spirit will be a firm and fixed spirit, and will uphold us. The more cheerful we are in our duty the more constant we shall be to it.

      II. See what David here promises, v. 13. Observe,

      1. What good work he promises to do: I will teach transgressors thy ways. David had been himself a transgressor, and therefore could speak experimentally to transgressors, and resolves, having himself found mercy with God in the way of repentance, to teach others God's ways, that is, (1.) Our way to God by repentance; he would teach others that had sinned to take the same course that he had taken, to humble themselves, to confess their sins, and seek God's face; and, (2.) God's way towards us in pardoning mercy; how ready he is to receive those that return to him. He taught the former by his own example, for the direction of sinners in repenting; he taught the latter by his own experience, for their encouragement. By this psalm he is, and will be to the world's end, teaching transgressors, telling them what God had done for his soul. Note, Penitents should be preachers. Solomon was so, and blessed Paul.

      2. What good effect he promises himself from his doing this: "Sinners shall be converted unto thee, and shall neither persist in their wanderings from thee, nor despair of finding mercy in their returns to thee." The great thing to be aimed at in teaching transgressors is their conversion to God; that is a happy point gained, and happy are those that are instrumental to contribute towards it, Jam. v. 20.

      14 Deliver me from bloodguiltiness, O God, thou God of my salvation: and my tongue shall sing aloud of thy righteousness.   15 O Lord, open thou my lips; and my mouth shall show forth thy praise.   16 For thou desirest not sacrifice; else would I give it: thou delightest not in burnt offering.   17 The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise.   18 Do good in thy good pleasure unto Zion: build thou the walls of Jerusalem.   19 Then shalt thou be pleased with the sacrifices of righteousness, with burnt offering and whole burnt offering: then shall they offer bullocks upon thine altar.

      I. David prays against the guilt of sin, and prays for the grace of God, enforcing both petitions from a plea taken from the glory of God, which he promises with thankfulness to show forth. 1. He prays against the guilt of sin, that he might be delivered from that, and promises that then he would praise God, v. 14. The particular sin he prays against is blood-guiltiness, the sin he had now been guilty of, having slain Uriah with the sword of the children of Ammon. Hitherto perhaps he had stopped the mouth of conscience with that frivolous excuse, that he did not kill him himself; but now he was convinced that he was the murderer, and, hearing the blood cry to God for vengeance, he cries to God for mercy: "Deliver me from blood-guiltiness; let me not lie under the guilt of this kind which I have contracted, but let it be pardoned to me, and let me never be left to myself to contract the like guilt again." Note, It concerns us all to pray earnestly against the guilt of blood. In this prayer he eyes God as the God of salvation. Note, Those to whom God is the God of salvation he will deliver from guilt; for the salvation he is the God of is salvation from sin. We may therefore plead this with him, "Lord, thou art the God of my salvation, therefore deliver me from the dominion of sin." He promises that, if God would deliver him, his tongue should sing aloud of his righteousness; God should have the glory both of pardoning mercy and of preventing grace. God's righteousness is often put for his grace, especially in the great business of justification and sanctification. This he would comfort himself in and therefore sing of; and this he would endeavour both to acquaint and to affect others with; he would sing aloud of it. This all those should do that have had the benefit of it, and owe their all to it. 2. He prays for the grace of God and promises to improve that grace to his glory (v. 15): "O Lord! open thou my lips, not only that I may teach and instruct sinners" (which the best preacher cannot do to any purpose unless God give him the opening of the mouth, and the tongue of the learned), "but that my mouth may show forth thy praise, not only that I may have abundant matter for praise, but a heart enlarged in praise." Guilt had closed his lips, had gone near to stop the mouth of prayer; he could not for shame, he could not for fear, come into the presence of that God whom he knew he had offended, much less speak to him; his heart condemned him, and therefore he had little confidence towards God. It cast a damp particularly upon his praises; when he had lost the joys of his salvation his harp was hung upon the willow-trees; therefore he prays, "Lord, open my life, put my heart in tune for praise again." To those that are tongue-tied by reason of guilt the assurance of the forgiveness of their sins says effectually, Ephphatha--Be opened; and, when the lips are opened, what should they speak but the praises of God, as Zacharias did? Luke i. 64.

      II. David offers the sacrifice of a penitent contrite heart, as that which he knew God would be pleased with. 1. He knew well that the sacrificing of beasts was in itself of no account with God (v. 16): Thou desirest not sacrifice (else would I give it with all my heart to obtain pardon and peace); thou delightest not in burnt-offering. Here see how glad David would have been to give thousands of rams to make atonement for sin. Those that are thoroughly convinced of their misery and danger by reason of sin would spare no cost to obtain the remission of it, Mic. vi. 6, 7. But see how little God valued this. As trials of obedience, and types of Christ, he did indeed require sacrifices to be offered; but he had no delight in them for any intrinsic worth or value they had. Sacrifice and offering thou wouldst not. As they cannot make satisfaction for sin, so God cannot take any satisfaction in them, any otherwise than as the offering of them is expressive of love and duty to him. 2. He knew also how acceptable true repentance is to God (v. 17): The sacrifices of God are a broken spirit. See here, (1.) What the good work is that is wrought in every true penitent--a broken spirit, a broken and a contrite heart. It is a work wrought upon the heart; that is it that God looks at, and requires, in all religious exercises, particularly in the exercises of repentance. It is a sharp work wrought there, no less than the breaking of the heart; not in despair (as we say, when a man is undone, His heart is broken), but in necessary humiliation and sorrow for sin. It is a heart breaking with itself, and breaking from its sin; it is a heart pliable to the word of God, and patient under the rod of God, a heart subdued and brought into obedience; it is a heart that is tender, like Josiah's, and trembles at God's word. Oh that there were such a heart in us! (2.) How graciously God is pleased to accept of this. It is the sacrifices of God, not one, but many; it is instead of all burnt-offering and sacrifice. The breaking of Christ's body for sin is the only sacrifice of atonement, for no sacrifice but that could take away sin; but the breaking of our hearts for sin is a sacrifice of acknowledgment, a sacrifice of God, for to him it is offered up; he requires it, he prepares it (he provides this lamb for a burnt-offering), and he will accept of it. That which pleased God was not the feeding of a beast, and making much of it, but killing it; so it is not the pampering of our flesh, but the mortifying of it, that God will accept. The sacrifice was bound, was bled, was burnt; so the penitent heart is bound by convictions, bleeds in contrition, and then burns in holy zeal against sin and for God. The sacrifice was offered upon the altar that sanctified the gift; so the broken heart is acceptable to God only through Jesus Christ; there is no true repentance without faith in him; and this is the sacrifice which he will not despise. Men despise that which is broken, but God will not. He despised the sacrifice of torn and broken beasts, but he will not despise that of a torn and broken heart. He will not overlook it; he will not refuse or reject it; though it make God no satisfaction for the wrong done him by sin, yet he does not despise it. The proud Pharisee despised the broken-hearted publican, and he thought very meanly of himself; but God did not despise him. More is implied than is expressed; the great God overlooks heaven and earth, to look with favour upon a broken and contrite heart, Isa. lxvi. 1, 2; lvii. 15.

      III. David intercedes for Zion and Jerusalem, with an eye to the honour of God. See what a concern he had,

      1. For the good of the church of God (v. 18): Do good in thy good pleasure unto Zion, that is, (1.) "To all the particular worshippers in Zion, to all that love and fear thy name; keep them from falling into such wounding wasting sins as these of mine; defend and succour all that fear thy name." Those that have been in spiritual troubles themselves know how to pity and pray for those that are in like manner afflicted. Or, (2.) To the public interests of Israel. David was sensible of the wrong he had done to Judah and Jerusalem by his sin, how it had weakened the hands and saddened the hearts of good people, and opened the mouths of their adversaries; he was likewise afraid lest, he being a public person, his sin should bring judgments upon the city and kingdom, and therefore he prays to God to secure and advance those public interests which he had damaged and endangered. He prays that God would prevent those national judgments which his sin had deserved, that he would continue those blessings, and carry on that good work, which it had threatened to retard and put a stop to. He prays, not only that God would do good to Zion, as he did to other places, by his providence, but that he would do it in his good pleasure, with the peculiar favour he bore to that place which he had chosen to put his name there, that the walls of Jerusalem, which perhaps were now in the building, might be built up, and that good work finished. Note, [1.] When we have most business of our own, and of greatest importance at the throne of grace, yet then we must not forget to pray for the church of God; nay, or Master has taught us in our daily prayers to begin with that, Hallowed be thy name, Thy kingdom come. [2.] The consideration of the prejudice we have done to the public interests by our sins should engage us to do them all the service we can, particularly by our prayers.

      2. For the honour of the churches of God, v. 19. If God would show himself reconciled to him and his people, as he had prayed, then they should go on with the public services of his house, (1.) Cheerfully to themselves. The sense of God's goodness to them would enlarge their hearts in all the instances and expressions of thankfulness and obedience. They will then come to his tabernacle with burnt-offerings, with whole burnt-offerings, which were intended purely for the glory of God, and they shall offer, not lambs and rams only, but bullocks, the costliest sacrifices, upon his altar. (2.) Acceptably to God: "Thou shalt be pleased with them, that is, we shall have reason to hope so when we perceive the sin taken away which threatened to hinder thy acceptance." Note, It is a great comfort to a good man to think of the communion that is between God and his people in their public assemblies, how he is honoured by their humble attendance on him and they are happy in his gracious acceptance of it.
