Joseph's family is known from the biblical story in the Book of Genesis. He was the favored son of Jacob, who had twelve sons in total. Joseph's mother was Rachel, and he had a special coat made for him, which caused jealousy among his brothers. Joseph's brothers, including Reuben, Simeon, and Judah, sold him into slavery out of envy. He eventually rose to power in Egypt and was reunited with his family during a famine. Joseph's story highlights themes of forgiveness and reconciliation within a family.
