John Calvin's Bible Commentary
Exodus 2:16
16.Now the priest of Midian. The profane would attribute this meeting to good fortune, whereas God affords us in it a striking picture of his providence, in thus with an outstretched hand directing the steps of his servant. Those damsels were in the habit of coming daily to the well; and Moses sat down to ask for hospitality at the waterside, whither in a dry country the inhabitants were likely to flock in the evening. But it was by no means due to chance that he came so opportunely to render assistance to the damsels, and that Jethro so hospitably invited him; but God was the guide of his wandering servant’s way, not only to obtain for him a resting-place for a day, but a comfortable habitation even to the close of his exile. For Jethro (whose title shews that he was of some dignity amongst his people) not only engaged his services, but chose him for his son-in-law. Although the occupation of a shepherd was a humble one, yet there was no little consolation in this high connection. All are not agreed about the word כהן, cohen (29) The Chaldee paraphrast badly translates it “Prince,” because it does not accord with the fact that the shepherds of the country were at variance with his daughters. Nor is it more probable that a rich and chief man would have been without servants, so as to be obliged to expose his daughters daily to the insults and quarrels of the shepherds. I think, then, that he was a priest ( sacrificum,) which is the opinion most generally received. But the question is, whether he worshipped false gods, or the one true God? and certainly many probable reasons lead us to conclude, that he did not sacrifice to idols; because Moses could scarcely have been persuaded, not merely to live in a house which was defiled by foul unrighteousness, but even to marry into it. Besides, hereafter, many indications of piety will appear in the language of Jethro. Although, as almost the whole world had then fallen into many corrupt practices, it seems likely to me that his priesthood was in some measure corrupted. In the time of Abraham, Melehizedek was the only priest of the living God. Abraham himself was extricated from a deep abyss of idolatry into which his family was plunged. It was, then, hardly possible that the Midianites should have retained the pure worship; and indeed it is plain from other passages, that they were joined to idols. After duly weighing all these points, nothing occurs to me as more probable, than that under the priesthood of Jethro the true God was worshipped, according as tradition had revealed Him, but not purely; because religion was at that time everywhere contaminated by diverse superstitions. But there is some difference between idolatry and the impure worship of God, corrupted in some respects. I say, then, that they were worshippers of the true God, because they had not entirely departed from the principles of His religion, although they had contracted some defilement from the stinking puddles of error which had gradually crept in. There is also another question among interpreters as to the name “Jethro.” Those who think Bethuel (30) was a different person from Jethro, are easily refuted; for it is quite evident, that Moses in the next chapter speaks of the same person, though under another name. Nor would it agree with the mention of his marriage, that the name of the father should be altogether omitted; and it is a forced construction to suppose, that in such immediate connection two persons should be spoken of as in the same degree of relationship. Again, if Jethro was the son of Bethuel, living in the same house, he would have been a member of the family, but not its head, and therefore Moses would not be said to have fed his flock. Besides, it is probable that Hobab (who will be afterwards called the son of Bethuel, Numbers 10:29) was the brother-in-law of Moses, i e. , the brother of his wife; from whence we collect, that Jethro, as is not unusual, had two names. For it is absurd to think that it is Hobab whom Moses here calls Jethro, and an unreasonable invention. We shall hereafter see that Jethro came into the Desert to congratulate Moses; but it is related in the same place that he “let him depart;” and certainly it would not have been kind to press a man bowed down by age to accompany him on his long journey. For if he was older than Moses, he was scarcely less than ninety; and what sense would there have been in promising a decrepit old man the reward of his labor, after they should reach the land of Canaan?
But the whole controversy is put an end to in one word; because Moses writes that Jethro returned home, but that Hobab was persuaded to listen to his earnest requests, and to remain with him. Nothing can be more probable than that the old man Bethuel, who was unequal to bear the fatigue of a long journey, returned straight home, having left his son behind with Moses, to be to him “instead of eyes,” and to guide them on their way.
