Deuteronomy 2:9-13

And the LORD said unto me, Distress not the Moabites, neither contend with them in battle: for I will not give thee of their land for a possession; because I have given Ar unto the children of Lot for a possession.

The Emims dwelt therein in times past, a people great, and many, and tall, as the Anakims;

Which also were accounted giants, as the Anakims; but the Moabites call them Emims.

The Horims also dwelt in Seir beforetime; but the children of Esau succeeded them, when they had destroyed them from before them, and dwelt in their stead; as Israel did unto the land of his possession, which the LORD gave unto them.

Now rise up, said I, and get you over the brook Zered. And we went over the brook Zered.
