Numbers 22:4-5

Moab spoke to the leaders of Midian: “Look, this mob is going to clean us out—a bunch of crows picking a carcass clean.” Balak son of Zippor, who was king of Moab at that time, sent emissaries to get Balaam son of Beor, who lived at Pethor on the banks of the Euphrates River, his homeland.
