Moses Raises Joseph's Coffin From the Nile by the Explicit Name

"And Moses took the bones of Joseph," etc. This teaches that all Israel stretched out their hands to the spoil that they brought up from Egypt, but Moses busied himself only with a commandment. For when Joseph died and the Egyptians heard that he had made his brothers swear that they would not go up from Egypt until they took his bones up with them, they placed Joseph in a coffin of lead and cast it into the river Nile, and they said: From now on they will not be able to bring him up. And Moses wrote the Explicit Name and cast it into the Nile, and Joseph's coffin floated up upon the surface of the waters, and Moses stood and took it. "For he had surely sworn" — and why two oaths? Rather, he made his brothers swear that they would make their children swear. "From here with you" — this teaches that each and every tribe brought up its prince with it.
