Joseph, in the Bible, favored son of Jacob and Rachel. His brothers, jealous of his dreams and his coat of many colors, sold him into slavery. He was eventually taken to Egypt, where he became an influential member of the house of Potiphar. He was later unjustly imprisoned, on the basis of accusations made by Potiphar's wife. Joseph won his release by interpreting the pharaoh's dreams, and the pharaoh made him governor of Egypt. While holding that post, he rescued his family from famine.
