SEV Biblia, Chapter 4:20
Entonces Moisés tomó su mujer y sus hijos, y los puso sobre un asno, y volvió a tierra de Egipto; tomó también Moisés la vara de Dios en su mano.
Clarke's Bible Commentary - Exodus 4:20
Verse 20. His wife and his sons] Both Gershom and Eliezer, though the birth of the latter has not yet been mentioned in the Hebrew text. See the note on "chap. ii. 22". Set them upon an ass] The Septuagint reads the word in the plural, eki ta upozugia, upon asses, as it certainly required more than one to carry Zipporah, Gershom, and Eliezer.
The rod of God] The sign of sovereign power, by which he was to perform all his miracles; once the badge of his shepherd's office, and now that by which he is to feed, rule, and protect his people Israel.
Matthew Henry Commentary
Verses 18-23 - After God had appeared in the bush, he often spake to Moses. Pharao had hardened his own heart against the groans and cries of the oppressed Israelites; and now God, in the way of righteous judgment hardens his heart against the teaching of the miracles, and the terro of the plagues. But whether Pharaoh will hear, or whether he wil forbear, Moses must tell him, Thus saith the Lord. He must demand discharge for Israel, Let my son go; not only my servant, whom tho hast no right to detain, but my son. It is my son that serves me, an therefore must be spared, must be pleaded for. In case of refusal will slay thy son, even thy first-born. As men deal with God's people let them expect so to be dealt with.
