45:20-25 The nations are exhorted to draw near to Jehovah. None besides is able to help; he is the Saviour, who can save without the assistance of any, but without whom none can save. If the heart is brought into the obedience of Christ, the knee will cheerfully obey his commands. To Christ men shall come from every nation for blessings; all that hate his cause shall be put to shame, and all believers shall rejoice in him as their Friend and Portion. All must come to him: may we now come to him as the Lord our Righteousness, walking according to his commandments.
23. sworn by myself—equivalent to, "As I live," as Ro 14:11 quotes it. So Nu 14:21. God could swear by no greater, therefore He swears by Himself (Heb 6:13, 16).
word … in righteousness—rather, "the truth (see on [815]Isa 45:19) is gone forth from My mouth, the word (of promise), and it shall not return (that is, which shall not be revoked)" [Lowth]. But the accents favor English Version.
tongue … swear—namely, an oath of allegiance to God as their true King (see on [816]Isa 19:18; [817]Isa 65:16). Yet to be fulfilled (Zec 14:9).
