Deuteronomy 7:1-3

Devote the Nations to Destruction

“^aWhen Yahweh your God brings you into the land where you are entering to possess it, and He clears away many nations before you, the Hittites and the Girgashites and the Amorites and the Canaanites and the Perizzites and the Hivites and the Jebusites, ^bseven nations more numerous and stronger than you, 2 and when Yahweh your God gives them over before you and you strike them down, ^athen you shall devote them to destruction. ^bYou shall cut no covenant with them ^cand show no favor to them. 3 Furthermore, ^ayou shall not intermarry with them; you shall not give your ¹daughters to ²their sons, nor shall you take ³their daughters for your ⁴sons.
