Strong's Concordance #H6177
At least three Biblical cities are named Aroer.
A city named Aroer was located east of the Dead Sea and just north of the Arnon River. When Israel left Egypt, it was the capital of the land ruled by Amorite King Sihon (Deuteronomy 3:12, 4:48). After the Israelites defeated Sihon the city was given to the tribe of Reuben (Joshua 13:16).
Many years later the Ammonites (not to be confused with the Amorites) waged war against Israel claiming they stole Aroer and other lands from them (Judges 11). Jephthah, later to be a Judge of Israel, responded that God gave the land to Israel and it was therefore not stolen! He additionally pointed out that when it was conquered by God's people it was controlled by the Amorites and not them. Israel had a valid claim on the land since they had inhabited it for 300 years (Judges 11:26).
Another Aroer was located in the territory of Gad near the city of Rabbah (Joshua 13:25). Biblical commentaries disagree, however, whether this city, or another of the same name in Reuben's territory (mentioned above) was where Jephthah defeated the Ammonites (Judges 11:33). It was before this war that Jephthah made a vow some misinterpret as him willing to kill his own daughter if God made him victorious.
A third city called Aroer, located in Judah's territory, was one of the many places King David shared the spoils from one of his wars (1Samuel 30:28).
