Map of the twelve tribes of Israel; Reuben's supposed territory is shaded pale green. However, archeological scholars generally agree that Joshua is not a reliable source for reconstructing the history of the period it describes.[1]
According to the Hebrew Bible, the Tribe of Reuben (Hebrew: רְאוּבֵן, Modern: Rəʼūven, Tiberian: Rəʼūḇēn) was one of the twelve tribes of Israel. Unlike the majority of the tribes, the land of Reuben, along with that of Gad and half of Manasseh, was on the eastern side of the Jordan and shared a border with Moab. According to the biblical narrative, the Tribe of Reuben descended from Reuben, the eldest son of the patriarch Jacob. Reuben, along with nine other tribes, is reckoned by the Bible as part of the northern kingdom of Israel, and disappears from history with the demise of that kingdom in c. 723 BC.
