Pethor or Petor (פְּתוֹר) in the Hebrew Bible is the home of the prophet Balaam. In the Book of Numbers, Pethor is described as being located "by the river of the land of the children of his people". The Bible usually uses the name "the River" to the Euphrates; the rest of the description is somewhat vague and perhaps corrupted. In Deuteronomy, Balaam is from "Pethor of Aram-Naharaim" in Upper Mesopotamia. It is widely accepted that Pethor is the town Pitru, which is mentioned in ancient Assyrian records.
