Reuben or Reuven was the first of the six sons of Jacob and Leah, according to the Book of Genesis. He was the founder of the Israelite Tribe of Reuben.

Jacob, later given the name Israel, is regarded as a patriarch of the Israelites and is an important figure in Abrahamic religions, such as Judaism, Samaritanism, Christianity, and Islam. Jacob first appears in the Book of Genesis, originating from the Hebrew tradition in the Torah. Described as the son of Isaac and Rebecca, and the grandson of Abraham, Sarah, and Bethuel, Jacob is presented as the second-born among Isaac's children. His fraternal twin brother is the elder, named Esau, according to the biblical account. Jacob is said to have bought Esau's birthright and, with his mother's help, deceived his aging father to bless him instead of Esau. Later in the narrative, following a severe drought in his homeland of Canaan, Jacob and his descendants, with the help of his son Joseph, moved to Egypt where Jacob died at the age of 147. He is supposed to have been buried in the Cave of Machpelah.
