'O God' in the Bible

They sacrificed unto demons who are not +God; To gods whom they knew not, To new ones, who came newly up, Whom your fathers revered not.

They have moved me to jealousy with that which is no God; They have exasperated me with their vanities; And I will move them to jealousy with that which is not a people; With a foolish nation will I provoke them to anger.

See now that I, I am HE, And there is no god with me; I kill, and I make alive; I wound, and I heal, And there is none that delivereth out of my hand,
