Exodus 4:20

"And Moses took his wife and his sons, and set them upon an ass, and he returned to the land of Egypt: And Moses took the rod of God in his hand."

"Wife and his sons ..." This is the first mention of any son except Gershom, but we learn the name of the other son, Eliezer, in Exodus 18:4. Note the change of pronouns in this verse. Of his family, it says that he set them upon an ass; but it is not said that they returned to Egypt, but that he (Moses) did so. The explanation of this immediately appears in the text."

"Set them upon an ass ..." Here again, the quibblers like to comment on the size of such an ass! that Moses could put his whole family on it. However, "according to Hebrew idiom, this means that he set them upon asses."[25] In view of this fact, universally known (except to critics), the Septuagint (LXX) renders the plural here: "Moses took his wife and children, and mounted them on the beasts."

"And he took the rod of God in his hand ..." Incredibly, Harford and others find this to be in conflict with the rod Moses already possessed. See comment under Exodus 4:9, above. In God's use of Moses' shepherd's staff, not merely for more firmly establishing his faith, but also for use in future "signs" (plural) to be wrought against Egypt, God had clearly made the rod, His rod, God's instrument in the hands of God's instrument (Moses). Indeed it was the rod of God!
