Exodus 34:12-16

12“Be very careful never to make a treaty with the people who live in the land where you are going. If you do, you will follow their evil ways and be trapped.

13Instead, you must break down their pagan altars, smash their sacred pillars, and cut down their Asherah poles.

14You must worship no other gods, for the Lord, whose very name is Jealous, is a God who is jealous about his relationship with you.

15“You must not make a treaty of any kind with the people living in the land. They lust after their gods, offering sacrifices to them. They will invite you to join them in their sacrificial meals, and you will go with them.

16Then you will accept their daughters, who sacrifice to other gods, as wives for your sons. And they will seduce your sons to commit adultery against me by worshiping other gods.
