'O God' in the Bible

Do not show partiality when deciding a case; listen to small and great alike. Do not be intimidated by anyone, for judgment belongs to God. Bring me any case too difficult for you, and I will hear it.

They began to worship other gods, bowing down to gods they had not known—gods that the Lord had not permitted them to worship.

They sacrificed to demons, not God,to gods they had not known,new gods that had just arrived,which your fathers did not fear.

See now that I alone am He;there is no God but Me.I bring death and I give life;I wound and I heal.No one can rescue anyone from My hand.
