5:11 Old corn - The corn of the last year, which the inhabitants of those parts had left in their barns, being fled into their strong cities, or other remoter parts. The morrow - That is, on the sixteenth day; for the passover was killed between the two evenings of the fourteenth day, and was eaten in that evening or night, which, according to the Jewish computation, whereby they begin their days at the evening, was a part of the fifteenth day, all which was the feast of the passover; and so the morrow of the sixteenth day, was the morrow after the passover, when they were obliged to offer unto God the first sheaf, and then were allowed to eat of the rest. Parched corn - Of that year's corn. which was most proper for that use. Self - same day - Having an eager desire to enjoy the fruits of the land. And this corn came very seasonably; for after the passover, they were to keep the feast of unleavened bread, which they could not do, when they had nothing but manna to live upon.
5:10-12 A solemn passover was kept, at the time appointed by the law, in the plains of Jericho, in defiance of the Canaanites round about them. It was a performance of the promise, that when they went up to keep the feasts, their land should be under the special protection of the Divine providence, Ex 34:24. Notice is taken of the ceasing of the manna as soon as they had eaten the old corn of the land. For as it came just when they needed, so it continued as long as they needed it. This teaches us not to expect supplies by miracles, when they may be had in a common way. The word and ordinances of God are spiritual manna, with which God nourishes his people in this wilderness. Though often forfeited, yet they are continued while we are here; but when we come to the heavenly Canaan, this manna will cease, for we shall no longer need it.
