“Moses took his wife and his sons, and mounted them on a donkey, and he returned to the land of Egypt. Moses took the staff of God in his hand” (Exodus 4:20). “Moses took his wife and his sons” – why did he lead them there? It was so they would be with Israel to receive the Torah. “He mounted them on a donkey” – this is one of the eighteen matters that the Sages changed for King Ptolemy.6In the talmudic account of the writing of the Septuagint (Megilla 9a–b), the Sages changed “donkey” to “people carrier.” “Moses took the staff…” – he acted in accordance with what the Holy One blessed be He said to him: “You shall take this staff in your hand” (Exodus 4:17).
