'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.

Ye are my witnesses, says LORD, and my servant whom I have chosen, that ye may know and believe me, and understand that I am he. Before me there was no God formed, nor shall there be after me.

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

I am LORD, and there is none else. Besides me there is no God. I will gird thee, though thou have not known me,

Verily thou are a God who hides thyself, O God of Israel, the Savior.

By myself I have sworn, the word has gone forth from my mouth [in] righteousness, and shall not return, that to me every knee shall bow, every tongue will {confess to God (LXX/NT)}.

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

For from of old men have not heard, nor perceived by the ear, neither has the eye seen, O God, besides thee, [what] he has prepared for him who waits for him.
