12:37-42 The children of Israel set forward without delay. A mixed multitude went with them. Some, perhaps, willing to leave their country, laid waste by plagues; others, out of curiosity; perhaps a few out of love to them and their religion. But there were always those among the Israelites who were not Israelites. Thus there are still hypocrites in the church. This great event was 430 years from the promise made to Abraham: see Ga 3:17. So long the promise of a settlement was unfulfilled. But though God's promises are not performed quickly, they will be, in their season. This is that night of the Lord, that remarkable night, to be celebrated in all generations. The great things God does for his people, are to be not only a few days' wonder, but to be remembered throughout all ages; especially the work of our redemption by Christ. This first passover-night was a night of the Lord, much to be observed; but the last passover-night, in which Christ was betrayed and in which the first passover, with the rest of the Jewish ceremonies, was done away, was a night of the Lord, much more to be observed. Then a yoke, heavier than that of Egypt, was broken from off our necks, and a land, better than that of Canaan, set before us. It was a redemption to be celebrated in heaven, for ever and ever.

37. The children of Israel journeyed from Rameses—now generally identified with the ancient Heroopolis, and fixed at the modern Abu-Keisheid. This position agrees with the statement that the scene of the miraculous judgments against Pharaoh was "in the field of Zoan" [Ps 78:12, 43]. And it is probable that, in expectation of their departure, which the king on one pretext or another delayed, the Israelites had been assembled there as a general rendezvous. In journeying from Rameses to Palestine, there was a choice of two routes—the one along the shores of the Mediterranean to El-Arish, the other more circuitous round the head of the Red Sea and the desert of Sinai. The latter Moses was directed to take (Ex 13:17).

to Succoth—that is, booths, probably nothing more than a place of temporary encampment. The Hebrew word signifies a covering or shelter formed by the boughs of trees; and hence, in memory of this lodgment, the Israelites kept the feast of tabernacles yearly in this manner.

six hundred thousand … men—It appears from Nu 1:3 that the enumeration is of men above twenty years of age. Assuming, what is now ascertained by statistical tables, that the number of males above that age is as nearly as possible the half of the total number of males, the whole male population of Israel, on this computation, would amount to 1,200,000; and adding an equal number for women and children, the aggregate number of Israelites who left Egypt would be 2,400,000.
