Deuteronomy 2:10-12

10The Emim, a great and numerous people as tall as the Anakim, had previously lived there.

11They were also regarded as Rephaim, like the Anakim, though the Moabites called them Emim.

12The Horites had previously lived in Seir, but the descendants of Esau drove them out, destroying them completely and settling in their place, just as Israel did in the land of its possession the Lord gave them.
