Exodus 18:27 - Exposition

Moses let his father-in-law depart . Literally, "dismissed him," "sent him away." This single expression is quite enough to prove that the Hobab, whom Moses made strenuous efforts to keep with him after Sinai was left, is not the Jethro whom he was quite content to let go . He went his way into his own land . He returned to Midian, probably crossing the Elanitic gulf, which divided Midian from the Sinaitic region. The exact time of the departure is uncertain; but it was probably before the main events related in Exodus 19:1-25 .
