'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 Yahweh, "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 Yahweh, the King of Israel, and his Redeemer, Yahweh of Armies, says: "I am the first, and I am the last; and besides me there is no God.

I am Yahweh, and there is none else. Besides me, there is no God. I will strengthen you, though you have not known me;

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