'O God' in the Bible

and have cast their gods into the fire; for they were no gods, but the work of men's hands, wood and stone; therefore they have destroyed them.

"You are my witnesses," says the LORD, "With 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 will there be after me.

This is what the LORD, the King of Israel, and his Redeemer, the LORD of hosts, says: "I am the first, and I am the last; and besides me there is no God.

I am the LORD, and there is no other. Besides me, there is no God. I will strengthen you, though you have not known me;

Declare and bring it forth. Yes, let them take counsel together: who has shown this from ancient time? Who has declared it of old? Haven't I, the LORD? and there is no God else besides me, a just God and a Savior; there is no one besides me.

By myself have I sworn, the word is gone forth from my mouth in righteousness, and shall not return, that to me every knee shall bow, every tongue shall swear to God.

Yet they seek me daily, and delight to know my ways: as a nation that did righteousness, and did not forsake the ordinance of their God, they ask of me righteous judgments; they delight to draw near to God.
