TSK · Numbers 21:15

For a fire is gone out of Heshbon, A flame from the city of Sihon: It hath devoured Ar of Moab, The lords of the high places of the Arnon.

Thou art this day to pass over Ar, the border of Moab:

The burden of Moab. For in a night Ar of Moab is laid waste, [and] brought to nought; for in a night Kir of Moab is laid waste, [and] brought to nought.
