'O God' in the Bible

And suddenly there was with the angel a multitude of the heavenly host, praising God and saying, Glory to God in the highest;

But where are the nine? There are not found to give glory to God, save this stranger.

And immediately he received his sight, and followed him, glorifying God: And all the people seeing it gave praise to God.

He said, Render therefore to C?sar the things which are C?sar's, and to God the things which are God's.
