What does Exodus 4:20 mean?
Moses is acting on God's command (Exodus 3:10) and returning to Egypt (Exodus 4:18–19). His father-in-law has given permission for the journey. Moses brings the staff which God commanded him to carry (Exodus 4:17). Along the way, God will provide Moses with more information about the coming clash with Egypt's king (Exodus 4:21–23).Zipporah is the wife given to Moses when he first went into exile (Exodus 2:21). The first child recorded from their marriage is Gershom (Exodus 2:22). Another son, Eliezer, will be mentioned later (Exodus 18:4). Assuming Zipporah was roughly the same age as Moses they both would have been around eighty years old (Exodus 7:7). The sons would have been no older than forty (Acts 7:23).
