Matthew Henry Commentary Joshua 5:10-12

"And the children of Israel encamped in Gilgal; and they kept the passover on the fourteenth day of the month at even in the plains of Jericho. And they did eat of the produce of the land on the morrow after the passover, unleavened cakes and parched grain, in the selfsame day. And the manna ceased on the morrow, after they had eaten of the produce of the land; neither had the children of Israel manna any more; but they did eat of the fruit of the land of Canaan that year." — Joshua 5:10-12 (ASV)

A solemn Passover was kept at the time appointed by the law, in the plains of Jericho, in defiance of the Canaanites around them. This fulfilled the promise (Exodus 34:24) that when they went up to keep the feasts, their land would be under the special protection of the Divine providence.

It is noted that the manna ceased as soon as they had eaten the old corn of the land. For it came just when they needed it, and so it continued only as long as they needed it. This teaches us not to expect supplies by miracles when they can be obtained through ordinary means.

The word and ordinances of God are spiritual manna, with which God nourishes his people in this wilderness. Although often forfeited, they are nevertheless continued while we are here; but when we come to the heavenly Canaan, this manna will cease, for we will no longer need it.
