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.

“This is what the Lord says—

Israel’s King and Redeemer, the Lord Almighty:

I am the first and I am the last;

apart from me there is no God.

Do not tremble, do not be afraid.

Did I not proclaim this and foretell it long ago?

You are my witnesses. Is there any God besides me?

No, there is no other Rock; I know not one.”
