'O God' in the Bible

For, in the days of David and Asaph, of old, there were chiefs of the singers, and songs of praise and thanksgiving, unto God.

Was it not, over these things, that Solomon king of Israel sinned - though, among many nations, there was no king such as he, and he was, beloved by his God, and so God gave him to be king over all Israel, - even him, did foreign women, cause to sin.
