Exodus 20:3

"Thou shalt have none other gods before me."

"Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve."

"There shall no strange god be in thee; neither shalt thou worship any strange god."

"Remember the former things of old: for I am God, and there is none else; I am God, and there is none like me,"

"Ye shall not go after other gods, of the gods of the people which are round about you;"

"And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might."

"And go not after other gods to serve them, and to worship them, and provoke me not to anger with the works of your hands; and I will do you no hurt."

"I have sent also unto you all my servants the prophets, rising up early and sending them, saying, Return ye now every man from his evil way, and amend your doings, and go not after other gods to serve them, and ye shall dwell in the land which I have given to you and to your fathers: but ye have not inclined your ear, nor hearkened unto me."
