How did Moses know where Joseph had been buried? They said: Serakh daughter, of Asher was of the same generation, and she went and said to Moses: "In the Nile River, Joseph is buried. And the Egyptians made for him metal skewers and affixed them with wood." Moses went and stood at the Nile River and said, "Joseph, the time has come for the Holy Blessed One to redeem Israel. Behold, the Shekhina is delayed for you, and the Israelites are delayed for you, and the clouds of glory are delayed for you. If you reveal yourself, good (okay!), and if not, we are cleansed of the oath which you have sworn upon our fathers." Then the coffin of Joseph floated to the surface and Moses took hold of it and went.
