Deuteronomy 2:11-12

DouayRheims(i) 11 They were esteemed as giants, and were like the sons of the Enacims. But the Moabites call them Emims. 12 The Horrhites also formerly dwelt in Seir: who being driven out and destroyed, the children of Esau dwelt there, as Israel did in the land of his possession, which the Lord gave him.
