The Ammonite king said to Jephthah's messengers, "Because Israel stole my land when they came up from Egypt -- from the Arnon River in the south to the Jabbok River in the north, and as far west as the Jordan. Now return it peaceably!"

They took all the Amorite territory from the Arnon River on the south to the Jabbok River on the north, from the desert in the east to the Jordan in the west.
