Komentaryo sa Josue 5:11: Tze'enah Ure'enah, Rashi, Metzudat David & Radak

“They ate the produce of the land” [5:11]. The Israelites ate the grain of the land of Israel the day after Passover. They brought the Omer offering from the new grain that they ate. Some sages say that they made unleavened bread from old grain, since they had not yet brought the Omer.⁶Radak, Joshua, 5:11.

From the day after the Pesach. This was the day of waving the Omer, for they sacrificed the Omer first.¹¹They could not have eaten from the new grain of Eretz Yisroel until after they brought the Omer sacrifice. See Vayikroh 23:14. From the seventh day of Adar, the day when Moshe died, when the manna stopped falling, they were sufficiently supplied with the manna which was in their vessels which they gathered on the seventh of Adar, as it is said, ‘They ate the manna for forty years.’¹²Shemos 16:35. But these forty years lacked thirty days— for the manna began to fall on the fifteenth day of Iyar.¹³Shemos 161, 13. See Rashi’s comments there. We must say therefore that in the [matzo] cakes the Bnei Yisroel took with them from Egypt, they tasted the taste of manna.

The day after day one of Pesach that this is the time of Korban Omer and the food will be perfect (able to be eaten)
