Deuteronomy 7:1-3

1“When the Lord your God brings you into the land you are about to enter and occupy, he will clear away many nations ahead of you: the Hittites, Girgashites, Amorites, Canaanites, Perizzites, Hivites, and Jebusites. These seven nations are greater and more numerous than you.

2When the Lord your God hands these nations over to you and you conquer them, you must completely destroy them. Make no treaties with them and show them no mercy.

3You must not intermarry with them. Do not let your daughters and sons marry their sons and daughters,
