You are my witnesses
"You are my witnesses," declares the Lord, "and my servant whom I have chosen, so that you may know and believe me and understand that I am he. Before me no god was formed, nor will there be one after me.
I, even I, am the Lord, and apart from me there is no savior.
I have revealed and saved and proclaimed— I, and not some foreign god among you. You are my witnesses," declares the Lord, "that I am God.
Yes, and from ancient days I am he. No one can deliver out of my hand. When I act, who can reverse it?"
Isaiah 43:10-13 NIV
