And the manna ceased after they ate of the corn of the land, neither did the children of Israel use that food any more, but they ate of the corn of the present year of the land of Chanaan.

“No longer did the Bnei Yisroel have manna. Therefore they ate of the grain of the land. If they would have had manna they would not have eaten of the grain, for the manna was agreeable to them. There is a parable for this: One says to a child, “Why are you eating barley bread?” “Because I have no wheat bread.” That is why it is said, ‘no longer did etc.’”

“And the manna ceased on the morrow after they had eaten of the old corn of the land,.... There being now no further need of it; miracles are not wrought or continued when unnecessary; for the ceasing of the manna shows, that it was not a common but an extraordinary provision. The ceasing of the manna, which was a type of Christ, may signify the cessation of Gospel ordinances, in which Christ is held forth as food for his people. These are to continue till all the spiritual Israel of God have passed over the river Jordan, or death, even until the end of the world, and then to cease, Mat 28:19; the eating of the old corn may signify the glories of the future state, the joys and happiness of the heavenly Canaan, prepared for those that love the Lord from the foundation of the world; it may denote those ancient things the saints will feed and live upon to all eternity; the eternal love of the three divine Persons, electing grace, the ancient settlements of grace, the everlasting covenant of grace, and the blessings of it; the glorious Mediator of it, that was set up from everlasting, and the grace given to them in him before the world began: neither had the children of Israel manna any more; having no more need of it, as the saints in heaven will stand in no more need of Gospel ordinances: but they did eat of the fruit of the land of Canaan that year; the increase of the land, not only of the fields, but of the vineyards and oliveyards, which they had neither sown nor planted, see Deu 6:10; which may denote the plenty and variety of the joys of heaven, and glories of the future state; the various fruits which grow on Christ, the tree of life, brought forth every month, or continually; all which will be enjoyed through the free grace of God, without the works or merits of men.”

“And the manna ceased - after they had eaten of the old corn - This miraculous supply continued with them as long as they needed it. While they were in the wilderness they required such a provision; nor could such a multitude, in such a place, be supported without a miracle. Now they are got into the promised land, the anathematized inhabitants of which either fall or flee before them, they find an old stock, and they are brought in just at the commencement of the harvest; hence, as there is an ample provision made in the ordinary way of Providence, there is no longer any need of a miraculous supply; therefore the manna ceased which they had enjoyed for forty years. The circumstances in which it was first given, its continuance with them through all their peregrinations in the wilderness, its accompanying them over Jordan, and ceasing as soon as they got a supply in the ordinary way of Providence, all prove that it was a preternatural gift. "On the fourteenth of Nisan they sacrificed the paschal lamb: on the fifteenth, i.e., according to our calculation, the same day after sunset, they disposed themselves for eating it, and actually did eat it. On the morrow, the sixteenth, after having offered to God the homer, they began eating the corn of the country; and the seventeenth, the manna ceased to fall from heaven. What supports this calculation is, that the homer or sheaf was offered the sixteenth of Nisan, in broad daylight, though pretty late. Now the manna did not fall till night, or very early in the morning; so that it cannot be said to have ceased falling the same day that the Israelites began to eat of the produce of the country." - Dodd.”

“Land. The Septuagint intimate on the 15th. The Hebrew seems to say the 16th, Nisan, “on the morrow after they had eaten of the (old) corn.” (Calmet) — Grabe’s Septuagint agrees with the Vulgate and Hebrew, and specifies that the Israelites “eat of the corn of the country on the day after the Passover, unleavened and new. On that day, the morrow, manna ceased.” All depends on the determination of the first day of the festival. If we date from the eating of the paschal lamb on the 14th, or from the solemn day, which was the 15th, manna must have been withdrawn either on the 15th or 16th of the month; though Salien thinks that it ceased as soon as the Israelites had begun to eat of the fruit of the country, on the eastern side of the Jordan. This miraculous food was withholden as soon as the Israelites entered the land of promise; and so the blessed Eucharist, of which it was a figure, and all the sacraments, will cease, when the Christian people shall have taken possession of their heavenly country.
