'O God' in the Bible

Then they called a second time for the man that had been blind, and said to him, Give glory to God: for we know that this man is a great sinner.

who knew that the Father had given all things into his hands, and that He came from God, and was going to God,

for they will excommunicate you: yea, the time is coming, that whosoever killeth you, will think that he offers an acceptable service to God.
