Aroer: ruins.

1. A town on the north bank of the Arnon (Deuteronomy 4:48; Judges 11:26; 2 Kings 10:33), the southern boundary of the kingdom of Sihon (Joshua 12:2). It is now called Arair, 13 miles west of the Dead Sea.
2. One of the towns built by the tribe of Gad (Numbers 32:34) "before Rabbah" (Joshua 13:25), the Ammonite capital. It was famous in the history of Jephthah (Judges 11:33) and of David (2 Samuel 24:5). (Comp. Isaiah 17:2; 2 Kings 15:29.)
3. A city in the south of Judah, 2 Kings 12 miles south-east of Beersheba, to which David sent presents after recovering the spoil from the Amalekites at Ziklag (1 Samuel 30:26,28). It was the native city of two of David's warriors (1 Chronicles 11:44). It is now called Ar'arah.
