Deuteronomy 2:10

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

The Emims dwelt there in time past,.... We read of them as early as the times of Chedorlaomer, Genesis 14:5 when their dwelling was in Kirjathaim, a city which Sihon king of the Amorites took from the Moabites, and which being taken from him, was with others given to the tribe of Reuben, Numbers 32:37. These are by some thought to be the same with the Yemim which Anah found and met with in the wilderness, and defeated, which we render "mules", Genesis 36:24. They had their name from the fear and terror they put men into because of their gigantic stature and great strength, as follows: it is probable they were the descendants of Ham:

a people great and many, and tall as the Anakims; who were very numerous, of a very bulky size of body, and of high stature, like the giants the spies had seen at Hebron, the sons of Anak, a noted giant there, Numbers 13:22.
