Benjamin was Joseph’s only full brother, both born to Rachel and Jacob, but Joseph had 10 half brothers, Reuben, Simeon, Levi, Judah, Issachar, Zebulon, Dan, Naphtali, Gad and Asher. Joseph’s father, Jacob, sired sons by four different women. Leah, his first wife, gave birth to six of Joseph's half brothers while Rachel's handmaid, Bilhah gave birth to two others. Two other half brothers were born to Leah's handmaid, Zilpah.
The story of Joseph’s birth is found in the Book of Genesis 30:22. The nation of Israel descends from the 12 sons of Jacob, considered the founders of the 12 Tribes of Israel. The Book of Genesis states that Joseph’s brothers were jealous of him because he was Jacob’s favorite son. As a result, they sold him into slavery to the Ishmaelites. Eventually, he was sold to Potiphar who had him imprisoned. After interpreting Pharaoh’s dreams, the Pharaoh rescued him and named him Vizier of Egypt.
Joseph saw his stepbrothers again when they arrived in Egypt during a famine. He imprisoned them because he wanted to see his brother Benjamin. The stepbrothers didn’t recognize him, but the family reunited when Joseph revealed his identify and forgave them for what they had done.
