Twelve Tribes of Israel, in the Bible, the Hebrew people who, after the death of Moses, took possession of the Promised Land of Canaan under the leadership of Joshua. Because the tribes were named after sons or grandsons of Jacob, whose name was changed to Israel after he wrestled an angel of the Lord, the Hebrew people became known as Israelites.

Jacob’s first wife, Leah, bore him six sons: Reuben, Simeon, Levi, Judah, Issachar, and Zebulun. Each was the father of a tribe, though Levi’s descendants (among whom were Moses and Aaron), the priests and temple functionaries, were dispersed among the other tribes and received no tribal land of their own. Two other tribes, Gad and Asher, were named after sons born to Jacob and Zilpah, Leah’s maidservant. Two additional tribes, Dan and Naphtali, were named after sons of Jacob born of Bilhah, the maidservant of Rachel, Jacob’s second wife. Rachel bore Jacob two sons, Joseph and Benjamin. The tribe of Benjamin provided Israel with its first king, Saul, and was later assimilated into the tribe of Judah. While no tribe bore the name of Joseph, two tribes were named after Joseph’s sons, Manasseh and Ephraim. The 10 tribes that settled in northern Palestine and were carried into captivity by the Assyrians became known as the Ten Lost Tribes of Israel.
