Exodus 18:3 - Exposition

And her two sons . That Zipporah had borne Moses at least two sons before his return to Egypt from Midian, had appeared from Exodus 4:20 . The name of the one, Gershom , and the ground of it, had been declared in Exodus 2:22 . The repetition here may be accounted for by the present chapter having been originally a distinct and separate composition, written on a distinct roll, and subsequently incorporated by Moses into his great work.
