Joshua 13:22-23

Balaam also the son of Beor, the soothsayer, did the children of Israel slay with the sword among them that were slain by them. {soothsayer: or, diviner} And the border of the children of Reuben was Jordan, and the border {thereof}. This {was} the inheritance of the children of Reuben after their families, the cities and the villages thereof.
