The Emims dwelt therein in times past. This is a confirmation of the foregoing declaration, which is, however, inserted by way of parenthesis by Moses himself; for the ninth verse, which I have just expounded, is followed regularly by the thirteenth, "Now rise up," etc. For, after God had turned away the people from the borders of Moab, He shews them in what direction they must pass over; but Moses, interrupting the address of God, explains how the Moabites had obtained that territow, though they were strangers, and had no land of their own on which they might set their foot;. For Lot was no less an alien than Abraham; Moses, therefore, states how by special privilege the posterity of Lot became masters of that land which giants had previously possessed. For it was not by human means that, having driven out the giants, who were formidable to all men, they had obtained the peaceful occupation, and even the dominion of that land, which might have seemed to be invincible, from the valor and strength of its inhabitants. He says, therefore, that the giants dwelt there, as also in Mount Seir; and that both were overcome and destroyed, not so much by the hand and arms of men as by the power of God, so that their land might be cleared for possession as well for the children of Esau as for those of Lot. Now, since God elsewhere declares that He had given Mount Seir to Esau as an inheritance, according as He had promised to his father Isaac, it follows that the Moabites had obtained their land also by the same Divine authority. The comparison which is made between Edom and the Israelites does not hold good in all respects; for, although Esau was sustained by this consolation, that his inheritance should be of "the fatness of the earth," (Genesis 27:39,) it might still be the case that with regard to himself and his posterity, their possession should not be legitimate; whereas God so promised the land of Canaan to the race of Abraham, that the Israelites received the dominion over it, as if from His own hand, as it is said in Psalm 136:21. In this respect, too, there was a difference, because the land of Canaan was chosen as that in which God should gather His Church, in which He should be purely worshipped, and which should be an earnest, to the faithful of the heavenly and eternal rest. But, as elsewhere, the distinction between the sons of Esau and Jacob is marked, so now Moses magnifies God's special blessing towards them both.

For the Emims, Horims, and Anakims, see the marginal references. These verses are either parenthetical or the insertion of a later hand.

The Emims dwelt therein - Calmet supposes that these people were destroyed in the war made against them by Chedorlaomer and his allies, Genesis 14:5. Lot possessed their country after the destruction of Sodom and Gomorrah. They are generally esteemed as giants; probably they were a hardy, fierce, and terrible people, who lived, like the wandering Arabs, on the plunder of others. This was sufficient to gain them the appellation of giants, or men of prodigious stature. See next verse, Deuteronomy 2:11 (note).

The (f) Emims dwelt therein in times past, a people great, and many, and tall, as the Anakims;
(f) Signifying that as these giants were driven out for their sins: so the wicked when their sins are ripe, cannot avoid God's plagues.

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.

The Emims - Men terrible for stature and strength, as their very name imparts, whose expulsion by the Moabites is here noted as a great encouragement to the Israelites, for whose sake he would much more drive out the wicked and accursed Canaanites.
