'O God' in the Bible

Then Solomon said to God, "You yourself have shown steadfast loyal love to David my father and have made me king in his place.

And they buried him in the city of David with the kings, for he did good in Israel and with respect to God and his house.

So now, do not let Hezekiah deceive you. Do not let him urge you according to this. Do not put trust in him, for no god of any nation and kingdom has been able to save his people from my hand and from the hand of my ancestors. Surely then your God will not save you from my hand!'"
