'O God' in the Bible

And have given their gods to the fire: for they were no gods, but wood and stone, the work of men's hands; so they have given them to destruction.

You are my witnesses, says the Lord, and my servant whom I have taken for myself: so that you may see and have faith in me, and that it may be clear to you that I am he; before me there was no God formed, and there will not be after me.

The Lord, the King of Israel, even the Lord of armies who has taken up his cause, says, I am the first and the last, and there is no God but me.

I am the Lord, and there is no other; there is no God but me: I will make you ready for war, though you had no knowledge of me:

So that they may see from the east and from the west that there is no God but me: I am the Lord, and there is no other.

Give the word, put forward your cause, let us have a discussion together: who has given news of this in the past? who made it clear in early times? did not I, the Lord? and there is no God but me; a true God and a saviour; there is no other.

Though they make prayer to me every day, and take pleasure in the knowledge of my ways: like a nation which has done righteousness, and has not given up the rules of their God, they make requests to me for the right orders, it is their delight to come near to God.
