'Serve Other Gods' in the Bible

Therefore will I cast you out of this land into a land that you know not, neither you nor your fathers; and there shall you serve other gods day and night; where I will not show you favor.

Because of their wickedness which they have committed to provoke me to anger, in that they went to burn incense, and to serve other gods, whom they knew not, neither they, nor you, nor your fathers.
