Exodus 18:2 - Exposition

After he had sent her back . Literally "after her dismissal." It is curious that the fact of the dismissal had not been previously mentioned, yet is here assumed as known. Some commentators (as Knobel) find, in what is said of Zipporah, the trace of two distinct writers who give two contradictory narratives; but the difficulties and obscurities of the history are sufficiently intelligible, if we hear in mind—

1 . That Moses was addressing immediately those who knew the facts; and

2 . That he was studious of brevity.
