Deuteronomy 2:10-12

10(The Emim had dwelt there in times past, a people as great and numerous and tall as the Anakim.

11They were also regarded as giants, like the Anakim, but the Moabites call them Emim.

12The Horites formerly dwelt in Seir, but the descendants of Esau dispossessed them and destroyed them from before them, and dwelt in their place, just as Israel did to the land of their possession which the Lord gave them.)
