The Emims, means the terrible ones. The most profitable instruction to be gathered from these verses will be, I think, to remark how often places change their masters. Nations, like individuals, succeed one another in the events of life. Of all as well as one, it may be truly said, here we have no continuing city.

10 The Emims dwelt therein in times past, a people great, and many, and tall, as the Anakims;
11 Which also were accounted giants, as the Anakims; but the Moabites call them Emims.
12 The Horims also dwelt in Seir beforetime; but the children of Esau succeededc 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.
