22 Say not thou, I will recompense evil; but wait on the LORD, and he shall save thee.

      Those that live in this world must expect to have injuries done them, affronts given them, and trouble wrongfully created them, for we dwell among briers. Now here we are told what to do when we have wrong done us. 1. We must not avenge ourselves, no, nor so much as think of revenge, or design it: "Say not thou, no, not in thy heart, I will recompense evil for evil. Do not please thyself with the thought that some time or other thou shalt have an opportunity of being quits with him. Do not wish revenge, or hope for it, much less resolve upon it, no, not when the injury is fresh and the resentment of it most deep. Never say that thou wilt do a think which thou canst not in faith pray to God to assist thee in, and that thou canst not do in mediating revenge." 2. We must refer ourselves to God, and leave it to him to plead our cause, to maintain our right, and reckon with those that do us wrong in such a way and manner as he thinks fit and in his own due time: "Wait on the Lord, and attend his pleasure, acquiesce in his will, and he does not say that he will punish him that has injured thee (instead of desiring that thou must forgive him and pray for him), but he will save thee, and that is enough. He will protect thee, so that thy passing by one injury shall not (as is commonly feared) expose thee to another; nay, he will recompense good to thee, to balance thy trouble and encourage thy patience," as David hoped, when Shimei cursed him, 2 Sam. xvi. 12.

      17 Rejoice not when thine enemy falleth, and let not thine heart be glad when he stumbleth:   18 Lest the LORD see it, and it displease him, and he turn away his wrath from him.

      Here, 1. The pleasure we are apt to take in the troubles of an enemy is forbidden us. If any have done us an ill turn, or if we bear them ill-will only because they stand in our light or in our way, when any damage comes to them (suppose they fall), or any danger (suppose they stumble), our corrupt hearts are too apt to conceive a secret delight and satisfaction in it--Aha! so would we have it; they are entangled; the wilderness has shut them in--or, as Tyrus said concerning Jerusalem (Ezek. xxvi. 2) I shall be replenished, now she is laid waste. "Men hope in the ruin of their enemies or rivals to wreak their revenge or to find their account; but be not thou so inhuman; rejoice not when the worst enemy thou hast falls." There may be a holy joy in the destruction of God's enemies, as it tends to the glory of God and the welfare of the church (Ps. lviii. 10); but in the ruin of our enemies, as such, we must by no means rejoice; on the contrary, we must weep even with them when they weep (as David, Ps. xxxv. 13, 14), and that in sincerity, not so much as letting our hearts be secretly glad at their calamities. 2. The provocation which that pleasure gives to God is assigned as the reason of that prohibition: The Lord will see it, though it be hidden in the heart only, and it will displease him, as it will displease a prudent father to see one child triumph in the correction of another, which he ought to tremble at, and take warning by, not knowing how soon it may be his own case, he having so often deserved it. Solomon adds an argument ad hominem--addressed to the individual: "Thou canst not do a greater kindness to thy enemy, when he has fallen, than to rejoice in it; for them, to cross thee and vex thee, God will turn his wrath from him; for, as the wrath of man works not the righteousness of God, so the righteousness of God was never intended to gratify the wrath of man, and humour his foolish passions; rather than seem to do that he will adjourn the execution of his wrath: nay, it is implied that when he turns his wrath from him he will turn it against thee and the cup of trembling shall be put into thy hand."
