Deuteronomy 2:8-12

“So we passed beyond our brothers the sons of Esau, who live in Seir, away from the Arabah road, away from Elath and Ezion-geber. And we turned and passed through by the way of the wilderness of Moab.

Then the Lord said to me, ‘Do not attack Moab, nor provoke them to war, for I will not give you any of their land as a possession, because I have given Ar to the sons of Lot as a possession.’

(The Emim lived there previously, a people as great, numerous, and tall as the Anakim.

Like the Anakim, they too are regarded as Rephaim, but the Moabites call them Emim.

The Horites previously lived in Seir, but the sons of Esau dispossessed them and destroyed them from before them, and settled in their place; just as Israel did to the land of their possession which the Lord gave them.)
