Joseph was the favourite son out of all the 12 brothers and got given the special rainbow shirt, even though he was the 11th born. He was always telling the other brothers to bow down to him and they all got very annoyed.
The brothers wanted to kill him but Reuben says that to avoid having blood on their hands, they should throw him in the well instead.
The brothers kill a goat and put the blood o Joseph's rainbow coat. They bring the bloody coat to Jacob and tell him that Joseph was killed by a mountain lion.
Joseph then reveals himself. All the brothers celebrate together. They go back to tell Jacob. The Pharaoh then invites the whole family to live with him back in Egpt.
