1. When Jethro, the priest of Midian. This chapter consists of two parts. First of all, the arrival of Jethro in the camp is related, and his congratulation of Moses on account of the prosperity of his enterprise, together with the praise and sacrifice rendered to God.

3. And her two sons. It was remarked in its proper place, how distinguished a proof not only of faith, but of magnanimity and firmness Moses had manifested in giving these names to his sons.

5. And Jethro, Moses’ father-in-law. It was not so much love for Moses as the fame of the miracles which drew this old man, bowed down with age, from his home into the wilderness; for it will hereafter appear from the context, that he was not induced by ambition; because, after he had offered…

7. And Moses went out. In the foregoing verse he had related what happened last, viz., that Jethro said, I am come, and have brought to thee thy wife and children; but this transposition is common in Hebrew.

10. And Jethro said, Blessed. Hence it appears that although the worship of God was then everywhere profaned by strange additions, yet Jethro was not so devoted to superstition as not to acknowledge and honor the true God.

12. And Jethro. Although I do not think that Jethro had previously sacrificed to idols, yet, because he worshipped an unknown God, with but a confused and clouded faith, it appears that this was his first sincere and legitimate sacrifice since the God of Israel had been more clearly known to him.

13. And it came to pass. A memorable circumstance, and one well worth knowing, is here introduced. In that form of government over which God presided, and which He honored with extraordinary manifestations of His glory, there was something deserving of reprehension, which Jethro corrected; and…

15. And Moses said unto his father-in-law. Moses replies ingenuously, as if on a very praiseworthy matter, like one unconscious of any fault; for he declared himself to be the minister of God, and the organ of His Spirit. Nor, indeed, could his faithfulness and integrity be called in question.

17. And Moses’ father-in-law said. He does not absolutely condemn the whole system which Moses had before adopted, after the manner of morose, or froward, or ambitious men who, by carping at some trifle, obscure the noble deeds of others; but by seeking only to correct a part of it, he detracts not…

19. I will give thee counsel. Jethro dares, indeed, to promise success, if Moses will obey his counsel; yet does he not proudly boast that this will be the fruit of his own prudence, but ascribes it to God’s blessing and grace, if he prospers even when nothing is established but on the best system.

21. Moreover, thou shalt provide out of all the people Literally so, “thou shalt provide;” meaning, thou shalt choose out, and take the most worthy, so that such an office be not entrusted rashly to any one that offers.

23. If thou shalt do this thing. What immediately follows, “and God command thee so,” may be taken in connection with the beginning of the verse, as if, in self-correction, Jethro made the limitation, that he did not wish his counsel to be obeyed, unless God should approve of it.

24. So Moses hearkened. Here is a. remarkable instance of modesty, that Moses is not indisposed to submit himself to the counsel of his father-in-law. For although Jethro was his superior in age and in degree of affinity, in other respects he was far inferior to him.
