Ar is mentioned in the Bible several times as a city of ancient Moab ([[s:Bible(King James)/Numbers#21 15|Numbers21 15]]). While the exact location is unknown, it was likely in the southern part of the Arnon Valley. The city was one of Moab's most prominent, being listed by the prophet Isaiah in his denunciation of the Moabite nation ([[s:Bible(King James)/Isaiah#15 1|Isaiah15 1]]). The Bible later speaks of Ar as being captured by the Amorite King Sihon ([[s:Bible(King James)/Isaiah#21 28|Isaiah21 28]]). Modern scholars believe that the word "Ar" likely meant "city".
