AR . A city on the Arnon, the border between Moab and the Amorites ( Numbers 21:15 , Deuteronomy 2:9 ), now Wâdy Môjib . It is called Ar Moab ( Numbers 21:28 , Isaiah 15:1 ),’ ÃŽ Moab ( Numbers 22:35 ), and ‘the city that is in the valley’ ( Deuteronomy 2:36 etc.). It is possibly the ruin seen by Burckhardt in the valley below the junction of the Lejjûn and the Môjib .
