Go not after other gods to serve them, and to worship them. Adore not your consciousness...

Thine, O LORD, is the greatness, and the power, and the glory, and the victory, and the majesty: for all that is in the heaven and in the earth is thine; thine is the kingdom, O LORD, and thou art exalted as head above all.
- 1 Chronicle 29: 11

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.
- Jeremiah 25: 6

Now the Spirit expressly states that in later times some will abandon the faith to follow deceitful spirits and the teachings of demons, influenced by the hypocrisy of liars, whose consciences are seared with a hot iron. They will prohibit marriage and require abstinence from certain foods that God has created to be received with thanksgiving by those who believe and know the truth
- 1 Timothy 4: 1-3

For thou shalt worship no other god: for the LORD, whose name is Jealous, is a jealous God: Lest thou make a covenant with the inhabitants of the land, and they go a whoring after their gods, and do sacrifice unto their gods, and one call thee, and thou eat of his sacrifice; And thou take of their daughters unto thy sons, and their daughters go a whoring after their gods, and make thy sons go a whoring after their gods. Thou shalt make thee no molten gods.
- Exodus 34: 14-17
