'No god' in the Bible

"You are my witnesses," declares the LORD, "and my servant whom I have chosen, so that you may know and trust me and understand that I am the One. Before me no God was formed, nor will there be one after me.

This is what the LORD says, the King of Israel and its Redeemer the LORD of the Heavenly Armies is his name "I am the first and I am the last, and apart from me there is no God.
