Ver. 9. I have given Ar unto the children of Lot— Ar, the capital of Moab, is here put for the whole country. Though the Moabites were now a wicked people; yet, for the sake of their pious ancestor, God would not have them dispossessed. Respecting the Emims, &c. mentioned in the following verses, see Genesis 14:5. The history of the expulsion of the Emims by the Moabites, and of the Horites by the Edomites, is no where else recorded: but it seems to be mentioned here, as an encouragement to the Israelites, not to fear the stoutest enemies that should oppose their taking possession of the promised land.
