Isaiah 45:23
KJV
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.
NIV
By myself I have sworn, my mouth has uttered in all integrity a word that will not be revoked: Before me every knee will bow; by me every tongue will swear.
The KJV’s “the word” preserves the force of a specific, irrevocable divine decree from the mouth of God, whereas “a word” makes it sound like merely one statement among many, weakening the solemn weight of God’s sworn oath in this prophecy.
