Exodus 34:12-14

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.
