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
