Tribe of Levi
According to the Bible, the Tribe of Levi is one of the tribes of Israel, traditionally descended from Levi, son of Jacob. The descendants of Aaron, who was the first kohen gadol (high priest) of Israel, were designated as the priestly class, the Kohanim.
The Tribe of Levi served particular religious duties for the Israelites and had political responsibilities as well. In return, the landed tribes were expected to give tithes to the Kohanim, the priests working in the Temple in Jerusalem, particularly the tithe known as the Maaser Rishon. The Levites who were not Kohanim played music in the Temple or served as guards. When Joshua led the Israelites into the land of Canaan the Levites were the only Israelite tribe that received cities but were not allowed to be landowners, because "the Lord God of Israel is their inheritance, as he said to them" (Book of Joshua, Joshua 13:33).
Notable descendants of the Levite lineage according to the Bible include Moses, Aaron, Miriam, Samuel, Ezekiel, Ezra, and Malachi.
