Psalms 24:5
5. righteousness—the rewards which God bestows on His people, or the grace to secure those rewards as well as the result.
Isaiah 12:2
2. Lord JEHOVAH —Jah, Jehovah. The repetition of the name denotes emphasis, and the unchangeableness of God's character.
strength . . . song . . . salvation—derived from Ex 15:2; Ps 118:14. The idea of salvation was peculiarly associated with the feast of tabernacles (see Isa 12:3). Hence the cry "Hosanna," "Save, we beseech thee," that accompanied Jesus' triumphal entry into Jerusalem on that day (the fifteenth of the seventh month) (Mt 21:9; compare with Ps 118:25, 26); the earnest of the perfected "salvation" which He shall bring to His people at His glorious second appearance at Jerusalem (Heb 9:28). "He shall appear the second time without sin unto salvation." Compare Re 21:3, "The tabernacle of God is with men." Compare Lu 9:33, "three tabernacles: one for thee," &c. (the transfiguration being a pledge of the future kingdom), (Ps 118:15; Zec 14:16). As the Jew was reminded by the feast of tabernacles of his wanderings in tents in the wilderness, so the Jew-Gentile Church to come shall call to mind, with thanksgiving, the various past ways whereby God has at last brought them to the heavenly "city of habitation" (Ps 107:7).Isaiah 45:15
15. God that hidest thyself—HORSLEY, after JEROME, explains this as the confession of Egypt, &c., that God is concealed in human form in the person of Jesus. Rather, connected with Isa 45:9, 10, the prophet, contemplating the wonderful issue of the seemingly dark counsels of God, implies a censure on those who presume to question God's dealings (Isa 55:8, 9; De 29:29). Faith still discerns, even under the veil, the covenant-keeping "God of Israel, the Saviour" (Isa 8:17).
Isaiah 45:21
21. Challenge the worshippers of idols (Isa 41:1).
take counsel together—as to the best arguments wherewith to defend the cause of idolatry. who . . . from that time— (Isa 41:22, 23; see on Isa 44:8). Which of the idols has done what God hath, namely, foretold, primarily as to Cyrus; ultimately as to the final restoration of Israel hereafter? The idolatry of Israel before Cyrus' time will have its counterpart in the Antichrist and the apostasy, which shall precede Christ's manifestation. just . . . and . . . Saviour—righteous in keeping His promises, and therefore a Saviour to His people. Not only is it not inconsistent with, but it is the result of, His righteousness, or justice, that He should save His redeemed (Isa 42:6, 21; Ps 85:10, 11; Ro 3:26).
