Matthew Henry on Exodus 18:1-6
This incident may very well be allowed to have happened as it is placed here, before the giving of the law, and not, as some place it, in connection with what is recorded, Num 10:11, Num 10:29, etc. Sacrifices were offered before; in these mentioned here (Exo 18:12) it is observable that Jethro is said to take them, not Aaron.
