You are my witnesses, says the LORD, and my servant whom I have chosen: that you 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 besides me there is no savior. I have declared, and have saved, and I proclaimed, when there was no strange god among you: therefore you are my witnesses, says the LORD, that I am God. ( (Isaiah 43:10-12)
