Emim signifies "the terrible," or "men of cubits or length." See Numbers xiii. 33. They had been probably ruined in the war of Chodorlahomor, (Genesis xiv. 5,) a little before the birth of Moab. (Calmet) --- But those few who remained, were sufficient to strike the beholders with terror, as they were not inferior to the other giants who were known, since the deluge, of the race of Enac, or of Rapha.
