What Does Exodus 4:18 Mean?

Moses went back to Jethro his father-in-law and said to him, "Please let me go back to my brothers in Egypt to see whether they are still alive." And Jethro said to Moses, "Go in peace." The first thing Moses does after the burning bush encounter is return to his obligations: he goes back to Jethro, his father-in-law, and asks for permission to leave.

This is not a sign of hesitation or wavering; it is the act of a man who understands that his relationship to Jethro and Jethro's household requires proper farewell and release before the mission to Egypt can begin. The extraordinary does not eliminate the ordinary obligations; Moses honors both.

Moses' phrasing is careful: he says he wants to return to "my brothers in Egypt to see whether they are still alive." He does not reveal the burning bush encounter or the divine mission to Jethro in this verse. The protective discretion may be diplomatic: the mission to Egypt is not something Jethro needs to authorize, and revealing it might make the departure seem more dangerous than Moses has indicated. Alternatively, Moses' description reflects the genuine uncertainty the long absence has produced: forty years have passed and he genuinely does not know who has survived.

Jethro's response, "Go in peace," is the blessing of a patriarch releasing a family member to pursue legitimate purposes. The phrase (Hebrew: lech leshalom) is a standard farewell that communicates reconciliation and goodwill: the departure is not conflict but proper conclusion. Jethro does not demand that Moses stay, does not cling to the productive son-in-law who has been managing his flocks, does not negotiate. His immediate release of Moses with a blessing is the human social sanction that matches the divine commission: Moses leaves Midian authorized from both directions.
