'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, saith Jehovah, 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, neither shall there be after me.

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

I am Jehovah, and there is none else; besides me there is no God. I will gird thee, though thou hast not known me;

Thus saith Jehovah, The labor of Egypt, and the merchandise of Ethiopia, and the Sabeans, men of stature, shall come over unto thee, and they shall be thine: they shall go after thee, in chains they shall come over; and they shall fall down unto thee, they shall make supplication unto thee,'saying , Surely God is in thee; and there is none else, there is no God.

Verily thou art a God that hidest thyself, O God of Israel, the Saviour.

Declare ye, and bring it forth; yea, let them take counsel together: who hath showed this from ancient time? who hath declared it of old? have not I, Jehovah? and there is no God else besides me, a just God and a Saviour; there is none besides me.

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 unto God.
