The Horites used to live in Seir, but the descendants of Esau claimed their land, wiped them out, and took their place, as Israel did in the land that the Lord gave them.
He gave these to the people when they were east of the Jordan River in the valley near Beth Peor, in the land of King Sihon of the Amorites, who ruled in Heshbon. Moses and Israel defeated him after they left Egypt.
