Exodus 18:5

And Jethro, Moses's father in law,.... This is the third time he is so called in the chapter already, and many more times besides after in it; the reason of which seems to be, either to distinguish him from another of the same name, or to do him honour, that he should be in such a relation to so great and distinguished a man as Moses now was: came with his sons and his wife unto Moses into the wilderness; not with his own sons and wife, but with the sons and wife of Moses; Zipporah and her sons, as before related; with those he came into the wilderness of Arabia, where Moses now was, and which was not at a great distance from Midian, since about the same spot Moses, when he dwelt there, had, and fed the flock of his father-in-law, Exodus 3:1, that part of the land of Midian where Jethro lived lay somewhere eastward of Mount Sinai, and was probably situated where Sharme now stands; which, according to Dr.

Pocock (i), is about a day and a half's journey from Mount Sinai, from whence the monks of Mount Sinai are chiefly supplied with fish (k): it follows: where he encamped at the mount of God: at Horeb, where the Lord had appeared to Moses; and so the Targum of Jonathan adds,"where the glory of the Lord was revealed to Moses at the beginning;''and where, afterwards, the Lord, appeared again, and gave the law, and therefore is called the Mount of God; the one as well as the other being past when Moses wrote this book, and called the mountain by this name: it is matter of question at what time Jethro came hither, whether before or after the giving of the law: it seems, by the order in which this story is here placed, as if it was immediately after the battle with Amalek; and Saadiah Gaon is of opinion it was before the giving of the law; and one would think it most reasonable and natural that Jethro would take the first opportunity of visiting Moses, and that Moses would not long defer sending for his wife and children: but Aben Ezra thinks he did not come till the second year after the tabernacle was set up, since, in the context, mention is made of burnt offerings and sacrifices, and no account is given of a new altar built by Moses; and besides, he says, "I do make them know the statutes of God and his laws", Exodus 18:16, and it is certain from hence, that the children of Israel were removed from Rephidim, and were now encamped at the mount of God, at Horeb; but whether they h

(5) Where he encamped at the mount of God. —It is quite possible that “the mount of God” may be here used, in a broad sense, of the entire Sinaitic mountain-region, as “wilderness” is just before used in the broad sense of the infertile region between Egypt and Palestine. Or the movement described in Exodus 19:1-2 may have taken place before Jethro’s arrival, though not related until after it. We must bear in mind that Exodus was probably composed in detached portions, and arranged afterwards. The present chapter has every appearance of being one such detached portion.

And Jethro, Moses' father in law, came with his sons and his wife unto Moses into the wilderness, where he encamped at the {b} mount of God: (b) Horeb is called the mount of God, because God did many miracles there. So Peter calls the mount where Christ was transfigured, the holy mount: for by Christ's presence it was holy for a time, 2Pe 1:18.

Jethro came, not at this time, but after the delivery of the law at Mount Sinai; as it may appear, 1. Because he finds them encamped, as it here follows, at the mount of God, i.e. Sinai, whither they came not till Exodus 19:2 . 2. Because the laws of sacrifices were given before his coming, as appears from Exodus 18:12 . 3. Because the execution of this counsel here given about the choice of magistrates, Exodus 18:19 , is related after the Israelites’ departure from Sinai, Deu 1:7 , &c. And therefore here is a transposal in this history, which is also frequent in other places of Holy Scripture.

5 . into the wilderness , &c.] The ‘mount of God’ ( Exodus 3:1 ) is Horeb, the ‘wilderness’ consequently can be only the ‘wilderness of Sinai,’ ‘in font of the mount,’ which, however, the Israelites do not reach till Exodus 19:1-2 , and which (if Rephidim be in W. Feiran, and Jebel Mûsâ be Sinai) was at least 24 miles beyond Rephidim (see on Exodus 19:1 b, 2). The passage affords a strong argument for the supposition (see above) that Exodus 18 stood originally at a later point in the narrative.

CHAPTER 18 Ex 18:1-27. Visit of Jethro. 1-5. Jethro … came … unto Moses, &c.—It is thought by many eminent commentators that this episode is inserted out of its chronological order, for it is described as occurring when the Israelites were "encamped at the mount of God." And yet they did not reach it till the third month after their departure from Egypt (Ex 19:1, 2; compare De 1:6, 9-15).
