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. Secondly, his proposed form of government for the people is set forth, in consequence of which judges and rulers were chosen, lest Moses should sink under his heavy task. The greater number of commentators think that Zipporah, having been enraged on account of her son’s circumcision, had turned back on their journey, and gone to live with her father; but to me this does not seem probable. For Moses would never have allowed his sons to be deprived of the redemption of which he was the minister; nor would it have been consistent that they should afterwards be appointed priests, of whom God was not the Redeemer. Besides, if he had deposited his wife and children in safety, and had advanced alone to the contest, he would have been deservedly suspected of deceit, or of excessive cowardice. Wherefore I have no doubt but that he underwent, together with his family, that miserable yoke of bondage by which they were long oppressed, and by this proof evidenced his faithfulness, so that greater authority might attend his vocation. The statement, then, in the second verse, “after he had sent her back,” I apply to Moses, because he had sent back his wife from the wilderness to visit her father, either having yielded to the desire which was natural to her as a woman, or, induced by his own feelings of piety, he had wished to show respect in this way to an old man nearly connected with him. There is something forced and cold in the words, which some would supply, “after he had sent back gifts.” The text runs very well thus, After Moses had sent back his wife, she was brought again by his father-in-law, thus returning and repaying his kindness.
