Joshua 5:11

They eat of the 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. On 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 sixteenth day was the morrow of 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.
