Levi. Levi was, according to the Book of Genesis, the third son of Jacob and Leah, and the founder of the Israelite Tribe of Levi and the grandfather of Aaron and Moses. Certain religious and political functions were reserved for the Levites. The Torah suggests that the name Levi refers to Leah's hope for Jacob to join with her, implying a derivation from yillaweh, meaning he will join, but scholars suspect that it may simply mean priest, either as a loan word from the Minaean lawi'u, meaning priest, or by referring to those people who were joined to the ark of the covenant. Another possibility is that the Levites originated as migrants, and that the name Levites indicates their joining with either the Israelites in general, or the earlier Israelite priesthood in particular.In the Book of it says that Levi was born in the new moon of the first month, which means that he was born on 1 Nissan. In the Book of Genesis, Levi and his brother, Simeon, exterminate the city of Shechem in revenge for the rape of Dinah, seizing the wealth of the city and killing the men. The brothers had earlier misled the inhabitants by consenting to Dinah's rapist marrying her, and when Jacob hears about their destruction of Shechem, he castigates them for it. In the Blessing of Jacob, Jacob is described as imposing a curse on the Levites, by which they would be scattered, in punishment for Levi's actions in Shechem. Some textual scholars date the Blessing of Jacob to a period between just one and two centuries prior to the Babylonian captivity, and some Biblical scholars regard this curse, and Dinah herself as an aetiological postdiction to explain the fates of the tribe of Simeon and the Levites, with one possible explanation of the Levites' scattered nature being that the priesthood was originally open to any tribe, but gradually became seen as a distinct tribe itself. Nevertheless, Isaac, Levi's grandfather, gives a special blessing about the lineage of priests of God. In the Book of Genesis, Levi is described as having fathered three sons, Gershon, Kohath, and Merari. A similar genealogy is given in the Book of Exodus, where it is added that among Kohath's sons was one, Amram, who married a woman named Jochebed, who was closely related to his father, and they were the biological parents of Moses, Aaron, and Miriam; though some Greek and Latin manuscripts of the Torah state that Jochebed was Amram's father's cousin, the Masoretic Text states that she was his father's sister, and the Septuagint mentions that she was one of his father's sisters. The Masoretic Text's version of Levi's genealogy thus implies that Levi also had a daughter, and the Septuagint implies further daughters. The names of Levi's sons, and possible daughter, are interpreted in classical rabbinical literature as being reflections on their future destiny. In some apocryphal texts such as the Testaments of the Twelve Patriarchs, and the Book of Jubilees, Levi's wife, his children's mother, is named as Milkah, a daughter of Aram.
