Isaiah 43:12
“I have declared, and have saved, and I have shewed, when there was no strange god among you: therefore ye are my witnesses, saith the Lord, that I am God.”
Ye are my witnesses, saith the Lord, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me.
I, even I, am the Lord; and beside me there is no saviour.
I have declared, and have saved, and I have shewed, when there was no strange god among you: therefore ye are my witnesses, saith the Lord, that I am God.
Yea, before the day was I am he; and there is none that can deliver out of my hand: I will work, and who shall let it?
Thus saith the Lord, your redeemer, the Holy One of Israel; For your sake I have sent to Babylon, and have brought down all their nobles, and the Chaldeans, whose cry is in the ships.
