THE DEPARTURE OF ISRAEL, THEIR NUMBERS, AND THE TIME OF THE EGYPTIAN SOJOURN.
(37-41) The two principal statements of this passage are — (1) that the sojourn of the Israelites in Egypt lasted four hundred and thirty years; and (2) that at the time of the departure the number of the “men” (gëbârim) was six hundred thousand. This latter statement is evidently a rough one, but it is confirmed, and even enlarged, by the more accurate estimate of Numbers 1:2, which goes into particulars with respect to the several tribes, and makes the exact amount of the adult male population, exclusive of the Levites, to be 625,540 (Numbers 2:32). It would follow that the nation, at the time of its departure, was one of above two millions of souls.
Two difficulties are raised with respect to this estimate: — (1) Could the Israelites possibly have increased during their sojourn in Egypt from the “seventy souls” who went down with Jacob to two millions? (2) Is it conceivable that such a multitude, with their flocks and herds, could have quitted Egypt on one day, and marched in a body through the narrow wadys of the Sinaitic region to the plain in front of Sinai? Could even that plain have contained them? With regard to the first point, before it can be decided we must ascertain what are the exact data. What is to be taken as the original number of those who “went down into Egypt?” what as the duration of the sojourn? It has been already shown (see the comment on Exodus 1:5) that the descendants of Jacob who entered Egypt were probably a hundred and thirty-two rather than seventy; that they were accompanied by their wives and husbands; that they took with them also their “households,” which were very numerous (see Note on Genesis 17:13); and that the entire number is fairly estimated at “several thousands.” Let us then place it at 3,000.
The duration of the sojourn in Egypt, stated in the Hebrew text at 430 years, is reduced by the LXX. and Samaritan Versions to half the time: i.e., to 215 years. If we accept Mr. Malthus’s statement, that in the absence of artificial checks population will double itself every twenty years, we shall find that 3,000 persons might, in the space of two centuries, increase to above 3,000,000; so that even the 215 years of the Greek and Samaritan Versions would admit of such a multiplication as that required. But as there is no sufficient reason for preferring the Versions to the Original, or the period of 215 to that of 430 years, we are entitled to regard the latter term as the real duration of the sojourn, in which case a doubling of the population every forty-five years would have produced the result indicated. Such a result under the circumstances, in the rich soil of Egypt, in the extensive territory granted to the Israelites, and with God’s special blessing on the people, is in no way surprising.
The difficulty of handling so vast a body, and marching them from Goshen to the Red Sea, and from the Red Sea to Sinai, remains, and, no doubt, is considerable. But we must remember that as far as Marah the country was perfectly open, and allowed of any extension of the line of march on either flank. After this, the wadys were entered, and the real difficulties of the journey began. Probably the host spread itself out, and proceeded to the rendezvous in front of the Ras Sufsafeh by several routes, of which Moses traces only the one which he himself followed. The plain Er-Rahah, according to the calculations of the best engineers, would have contained the entire multitude; but it is unnecessary to suppose that all were at any one time present in it. The whole Sinaitic district was probably occupied by the flocks and herds, and the herdsmen who tended them. Many of the tents may have been pitched in the Wady-ed-Deir and the Seil Leja. All that the narrative requires is that the main body of the people should have been encamped in front of Sinai, have heard the Decalogue delivered, and consented to the covenant.
