Deuteronomy 7:3-6

LITV(i) 3 nor shall you intermarry with them; you shall not give your daughter to his son, nor shall you take his daughter to your son. 4 For he will turn your son away from following Me, that they may serve other gods; and the anger of Jehovah will glow against you, and He will destroy you quickly. 5 But you shall deal with them in this way: you shall break down their altars, and dash in pieces the cult-stones; and you shall cut down their pillars; and you will burn their carved images with fire. 6 For you are a holy people to Jehovah your God. Jehovah your God has chosen you to be His own treasure out of all the people on the face of the earth.
