40. Now the sojourning of the children of Israel. The beginning of this period is not reckoned from the coming down of Jacob, for it is very clear from other passages, that, from the time that Jacob entered into Egypt to the Exodus, not more than 230 years at most had passed. (147) The Jews generally only reckon 210; but Moses includes also the period during which Abraham and his children were not in possession of the promised land. The meaning therefore is, that from the time that the inheritance of the land of Canaan was given to Abraham, the promise was suspended for 400, years before his posterity enjoyed their right. For Paul also thus explains this difficulty, (Galatians 3:17,) where he says, that God had confirmed his covenant with Abraham 430 years before the law was promulgated. Moses, therefore, dates the commencement of this period from the sojourning of Abraham, when he was still the lord of the land of Canaan by the just title of donation. With respect to the omission of the thirty years in the 15 chapter of Genesis, in this there is no contradiction, because the land had already been promised to Abraham some years previously, though, so far from obtaining dominion over it, he had scarcely been permitted to occupy it as “a stranger.” Therefore God apprizes him, that 400 years still remained before he would put his descendants into possession of it; and, consequently, that the little time which had elapsed was not sufficient for the trial of his patience, but that both for himself and for his posterity there was need of extraordinary endurance, lest they should faint under the weariness of the long delay. Moreover, there is no departure from the usual manner of speaking, in His not exactly reckoning the number of years. More than 400 years, some twenty, or thereabouts, indeed, remained; but, since God had no other object than to exhort His people to patience, He does not accurately compute or define the exact number of years, because it was sufficient to put before them 400 years in a round sum. In the same way, it is added in the next verse, “at the end of 430 years,” viz., from the time that Abraham had begun to be the legitimate lord of the land; for Moses wished to show, that although God had long delayed the fulfillment of His promise, still His truth and faithfulness were certainly proved, not only because He had precisely performed what He had proraised, but because He had observed the: foreappointed time. He calls the people, weak as they were, by an honorable title, “the hosts of the Lord,” both to enforce again the power of God’s blessing, and to give due honor to His grace in ruling and marshalling so confused a band. Although soldiers may be accustomed to obedience, and have learnt from exercise to keep their ranks; although they may have generals, commandants, and captains, and banners also under which to range themselves, still it is a very difficult thing to march an army of 20,000, or 30,000 men by night without. confusion, and in good order; how great a miracle was it, then, for 600,000 men, with women and children, much baggage, herds, and flocks, and other encumbrances, to pass by night through the midst of enemies, and all to escape safely without a single exception! To the same effect, Moses repeats in the last verse of this chapter, that “the Lord did bring the children of Israel out — by their armies,” as much as to say, that there was no confusion in that immense multitude; since God performed the part of an incomparable Leader in His marvelous power.
(147) This sentence is omitted in the French. The Latin is, “Hebraei communiter tantum decem recensent.” A reference, however, to R. Sal. Jarchi explains it, “you will find, (he says,) that from the arrival of the Israelites in Egypt to the time of their departure, was 210 years.” — In loco. Compare the LXX.
