“Which also were accounted giants, as the Anakims; but the Moabites call them Emims.”
King James Version (KJV)
2:9 Ar - The chief city of the Moabites, here put for the whole country which depended upon it. The children of Lot - So called to signify that this preservation, was not for their sakes, for they were a wicked people, but for Lot's sake whose memory God yet honours.
2:10 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.
2:12 Which the Lord gave - The past tense is here put for the future, will give after the manner of the prophets.
