(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.
Verse 5.- The wilderness. This term, which has the article, seems to be here used in that wide sense with which we are familiar from Exodus 3:18; Exodus 4:27;
Exodus 5:3; Exodus 7:16; etc. It is not" the wilderness of Sin," or "the wilderness of Sinai," that is intended, but generally the tract between Egypt and Palestine. Jethro, having entered this tract from Midian, had no difficulty in discovering from the inhabitants that Moses was encamped at the mount of God,—i.e; Sinai, and there sought and found him. There is no trace of any previous "engagement" to meet at a particular spot.
18:1-6 Jethro came to rejoice with Moses in the happiness of Israel, and to bring his wife and children to him. Moses must have his family with him, that while he ruled the church of God, he might set a good example in family government, 1Ti 3:5.
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 had got to the other side of the mount of Sinai as yet is not so clear; though it looks as if what Moses did, by the advice of Jethro, was after the law was given on Sinai, see Deuteronomy 1:6 so that, upon the whole, it seems as if this account, according to the order of time, should be placed after Numbers 10:28, or, as Dr. Lightfoot (l) thinks, between the tenth and eleventh verses of that chapter, and is put here to show that though Midian was near Amalek, as he observes, yet Jethro was exempt from the curse and destruction threatened to that, see 1 Samuel 15:6.
