Deuteronomy 7:1-3

Darby Translation

7 When Jehovah thy God shall bring thee into the land whither thou goest to possess it, and shall cast out many nations from before thee, the Hittites, and the Girgashites, and the Amorites, and the Canaanites, and the Perizzites, and the Hivites, and the Jebusites, seven nations greater and mightier than thou,

² and when Jehovah thy God shall give them up before thee and thou shalt smite them, then shalt thou utterly destroy them: thou shalt make no covenant with them, nor shew mercy unto them.

³ And thou shalt make no marriages with them: thy daughter thou shalt not give unto his son, nor take his daughter for thy son;
