'O God' in the Bible

Ye my witnesses, says Jehovah, and my servants whom I chose: so that ye shall know and trust to me, and understand that I am he: before me was no God formed, and after me shall be none.

Thus said Jehovah king of Israel, and Jehovah of armies, redeeming him, I the first and I the last; and besides me no God.

I am Jehovah, and none yet, no God besides me: I will gird thee and thou knewest me not:

This said Jehovah, The labor of Egypt and the gain of Cush, and of the Sabeans, men of measure, shall pass over upon thee, and to thee shall they be: after thee shall they come in fetters: they shall pass over and to thee shall they worship and supplicate to thee, Surely God is in thee, and none yet: no God.

Assemble ye together and come; draw ye near together, the escaped of the nations: they knew not lifting up the wood of their carved image, and praying to God he will not save.

Announce ye, and bring near; also ye shall take counsel together: who caused this to be heard from of old, from then announcing it? was it not I Jehovah? and no God more beside me; a just God and Saviour; none beside me.

Remember the former things from forever: for I am God and no god besides, and none like me.

From forever they heard not, they gave not ear, the eye saw not, O God, besides thee, he will do to him waiting for him.
