Judges 11:13; Judges 11:18

13 The king of the Ammonites answered Jephthah’s messengers, “When Israel came up out of Egypt, they took away my land from the Arnon to the Jabbok, all the way to the Jordan. Now give it back peaceably.”

18 “Next they traveled through the wilderness, skirted the lands of Edom and Moab, passed along the eastern side of the country of Moab, and camped on the other side of the Arnon. They did not enter the territory of Moab, for the Arnon was its border.
