'O God' in the Bible

Ye shall not look upon faces in judgment; as the small so the great shall ye hear; ye shall not be afraid of the face of man, for the judgment is to God; and the word which shall be hard for you, ye shall bring to me and I heard it

See ye now, that I, I am he, And no God with me: I will kill, and I will preserve alive; I struck through and through, and I will heal; And none takes away out of my hand.
