(a city), or Ar of Moab, one of the chief places of Moab. (Numbers 21:28; Isaiah 15:1) In later times the place known as Areopolis and Rabbath-Moab. The site still called Rabba . It lies about halfway between Kerak and the Wady Mojeb , 10 or 11 miles from each, the Roman road passing through it.
Ar
Ar is a city of Moab that Scripture mostly mentions as it falls. In Numbers 21 an old song about Sihon’s victory says, “there is a fire gone out of Heshbon, a flame from the city of Sihon: it hath consumed Ar of Moab.” The same song cries, “Woe to thee, Moab! thou art undone.” Numbers 21:15 puts Ar on the border of Moab. Centuries after, Isaiah’s burden against Moab opens with the city’s end: “in the night Ar of Moab is laid waste, and brought to silence.” Read Numbers 21:21-30 and then Isaiah 15.
