In the Judeo-Christian tradition, Levi (לוי "Attached", Standard Hebrew Levi, Tiberian Hebrew Lēwî) was the founder of the Levite tribe of Ancient Israel. He was a son of Jacob, also known as Israel, who was in turn a son of Isaac, the son of Abraham.
The tribe of the Levites gained no land when they entered Canaan. Instead, they were given the duty of priests and lived in the protection of various brother tribes where they taught the Torah, the Book of Law. The most famous Levite is Moses, who received the law from God on Mt. Sinai in the book of Exodus. His brother, Aaron became the first Levite priest of Israel.
