The story is in the book of Genesis. Joseph, son of Jacob, had 10 very jealous brothers. Joseph was his father's favorite son. His brothers decided to get rid of him. They sold him to some traders who took Joseph to Egypt. Joseph went through a lot in Egypt until he was able to decipher a dream for Pharoah. Pharoah made him his chief advisor. Then, there's a famine all over the Middle East. But Joseph forsaw this famine in Pharoah's dream. So food was rationed and saved from times of plenty. Jacob hears that there's lots of food in Egypt. So he sends his sons down to Egypt to buy food. After playing with their minds a bit, Joseph invites his brothers and their families to come to Egypt and settle in Goshen.
