Ar is mentioned in the Bible several times as a city of ancient Moab (Numbers 21:15). While the exact location is unknown, it was likely in the southern part of the Arnon Valley, which is the present day Wadi Mujib gorge in Jordan. The city was one of Moab's most prominent, being listed by the prophet Isaiah in his denunciation of the Moabite nation (Isaiah 15:1).
Modern scholars believe that the word "Ar" likely meant "city".
