Deuteronomy 7:2-5

NHEB(i) 2 and when the LORD your God shall deliver them up before you, and you shall strike them; then you shall utterly destroy them: you shall make no covenant with them, nor show mercy to them; 3 neither shall you make marriages with them; your daughter you shall not give to his son, nor shall you take his daughter for your son. 4 For he will turn away your son from following me, that he may serve other gods; so the anger of the LORD would be kindled against you, and he would destroy you quickly. 5 But you shall deal with them like this: you shall break down their altars, and dash their pillars in pieces, and cut down their Asherim, and burn their engraved images with fire.
