I am the LORD, and there is no other;

apart from me there is no God.

It seems like the people of Israel are having a hard time not turning away from God. They're making idols, And God is continually telling them that he is God. He said:

“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. Who then is like me? Let him proclaim it. Let him declare and lay out before me what has happened since I established my ancient people, and what is yet to come— yes, let him foretell what will come. 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.”
