Isaiah 45:23 · KJV


Context

21

Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the LORD? and there is no God else beside me; a just God and a Saviour; there is none beside me.

22

Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else.

23

I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear.

24

Surely, shall one say, in the LORD have I righteousness and strength: even to him shall men come; and all that are incensed against him shall be ashamed. Surely: or, Surely he shall say of me, In the LORD is all righteousness and strength righteousness: Heb. righteousnesses

25

In the LORD shall all the seed of Israel be justified, and shall glory.


Commentary

KJV Study Commentary
God swears by Himself (since none greater exists): 'I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return.' Every knee shall bow, every tongue swear allegiance to Him. Paul quotes this in Philippians 2:10-11 applying it to Christ, demonstrating Christ's full deity.

Historical & Cultural Context

The oath formula 'by myself' echoes God's oath to Abraham (Genesis 22:16). This adds solemn certainty to the promise of universal acknowledgment.

Reflection Questions

  1. How does Paul's application of this verse to Christ affirm Christ's deity?
  2. What does universal submission to God mean for those who refuse Him now?
