Midrasz do Ezechiela 37:19

Rabbi Levi said: That rod which was created in the twilight was delivered to the first man out of the garden of Eden. Adam delivered it to Enoch, and Enoch delivered it to Noah, and Noah [handed it on] to Shem. Shem passed it on to Abraham, Abraham [transmitted it] to Isaac, and Isaac [gave it over] to Jacob, and Jacob brought it down into Egypt and passed it on to his son Joseph, and when Joseph died and they pillaged his household goods, it was placed in the palace of Pharaoh. And Jethro was one of the magicians of Egypt, and he saw the rod and the letters which were upon it, and he desired in his heart (to have it), and he took it and brought it, and planted it in the midst of the garden of his house. No one was able to approach it any more.
