'O God' in the Bible

And as it seemed not good unto them to be a known of God, even so God delivered them up unto a lewd mind, that they should do those things which were not comely,

So shall every one of us give accounts of himself to God.

I have, therefore, whereof I may rejoice in Christ Jesus, in those things which pertain to God.

I beseech you brethren for our Lord Jesus Christ's sake, and for the love of the spirit, that ye help me in my business, with your prayers to God for me,
