Isaiah 15:1. “The burden of Moab. Because in the night Ar of Moab is laid waste, and brought to silence; because in the night Kir of Moab is laid waste, and brought to silence; He is gone up to Bajith, and to Dibon, the high places, to weep: Moab shall howl over Nebo, and over Medeba: on all their heads shall be baldness, and every beard cut off.
Moab was defeated by the Assyrians about the 4th year of Hezekiah’s reign, and the prophecies of 15:1-9 and 16:6-14 were then fulfilled.
Ar was the chief city of Moab. As you can see, it was situated near the Arnon River. Kir, another large city, lay about six miles south of Ar. Bajith and Debon were places of worship and sacrifice to the gods of the Moabites.
Those who will mourn the destruction of Moab are those who survived the devastation created by the Assyrians. Shaving one’s head and beard were signs of deep mourning.
Moab does not exist today as a country; rather, it is part of what we know as Jordan. Genesis 19: 37-38 is the account of Moab and Ammon, sons of Lot, conceived in incest by his elder and younger daughters after the destruction of Sodom and Gomorrah.
