Deuteronomy 7:5-6

5This is what you are to do to them: Break down their altars, smash their sacred stones, cut down their Asherah poles That is, wooden symbols of the goddess Asherah; here and elsewhere in Deuteronomy and burn their idols in the fire.

6For you are a people holy to the LORD your God. The LORD your God has chosen you out of all the peoples on the face of the earth to be his people, his treasured possession.
