Zipporah: "It is the rod that the Holy One, blessed be He, created in the twilight of the first Sabbath eve, and gave to Adam. He transmitted it to Enoch, from him it descended to Noah, then to Shem, and Abraham, and Isaac, and finally to Jacob, who brought it with him to Egypt, and gave it to his son Joseph. When Joseph died, the Egyptians pillaged his house, and the rod, which was in their booty, they brought to Pharaoh's palace.
At that time my father was one of the most prominent of the king's sacred scribes, and as such he had the opportunity of seeing the rod. He felt a great desire to possess it, and he stole it and took it to his house. On this rod the Ineffable Name is graven, and also the ten plagues that God will cause to visit the Egyptians in a future day. For many years it lay in my father's house.
One day he was walking in his garden carrying it, and he stuck it in the ground. When he attempted to draw it out again, he found that it had sprouted, and was putting forth blossoms. That is the rod with which he tries any that desire to marry his daughters. He insists that our suitors shall attempt to pull it out of the ground, but as soon as they touch it, it devours them."
