“When the a  Lord your God brings you into the land that you are entering to take possession of it, and clears away many nations before you, b the Hittites, the Girgashites, the Amorites, the Canaanites, the Perizzites, the Hivites, and the Jebusites, seven nations c more numerous and mightier than you, d and when the  Lord your God gives them over to you, and you defeat them, then you must e devote them to complete destruction.
That is, set apart ( devote) as an offering to the Lord (for destruction)
g You shall make no covenant with them and show no mercy to them.
h You shall not intermarry with them, giving your daughters to their sons or taking their daughters for your sons,
