Then Moses threw the second plate into the water, that with the figure of the eagle, repeating the same words, but again the coffin did not rise from the bed of the Nile, and there it remained, too, when he threw in the third plate bearing the figure of the bull, and called upon Joseph a third time to come forth. But the fourth plate with the human figure and the fourth invocation to Joseph brought the coffin to the surface of the water. Moses seized it, and in joy he bore it off. While Israel had been busy gathering gold and silver from the Egyptians, Moses had been thinking of nothing but Joseph's coffin, and his happiness was great that he had been permitted to fulfil the wish of Joseph.
