Isaiah 45:23

23 By myself have I taken an oath, a true word has gone from my mouth, and will not be changed, that to me every knee will be bent, and every tongue will give honour.

Isaiah 45:23 Meaning and Commentary

Isaiah 45:23

I have sworn by myself
Christ being the true God, he could swear by no greater, ( Hebrews 6:13 ) , this shows that what follows, and is here sworn unto, is of great importance, and strictly true, and would certainly be accomplished: the word is gone out of my mouth in righteousness;
both what goes before, that such that look unto him shall be saved; and also what follows, concerning the subjection of every creature to him; this was what he had resolved in his mind, and declared in his word, by promise and prophecy, should be; and as it was agreeably to truth and justice, it should certainly, and in faithfulness, be performed, and shall not return void and without effect, but be exactly and punctually accomplished: that unto me every knee shall bow, every tongue shall swear;
that is, everyone, or at least the generality of mankind, shall be subject to Christ, embrace his Gospel, submit to his ordinances, profess his name, and serve and worship him; this will be when the fulness of the Gentiles is brought in, and the Jews are converted: the apostle quotes this passage, and applies it to the judgment day, when all, whether they will or not, shall confess that Christ is God, which he so often asserts in this context; see ( Romans 14:10 Romans 14:11 ) ( Philippians 2:10 Philippians 2:11 ) .

Isaiah 45:23 In-Context

21 Give the word, put forward your cause, let us have a discussion together: who has given news of this in the past? who made it clear in early times? did not I, the Lord? and there is no God but me; a true God and a saviour; there is no other.

22 Let your hearts be turned to me, so that you may have salvation, all the ends of the earth: for I am God, and there is no other.

23 By myself have I taken an oath, a true word has gone from my mouth, and will not be changed, that to me every knee will be bent, and every tongue will give honour.

24 Only in the Lord will Jacob overcome and be strong: together all those who were angry with him will be put to shame and come to destruction.

25 In the Lord will all the seed of Israel get their rights, and they will give glory to him.
