it in suspense during the fifth hour, and needed to burn it at the beginning of the sixth hour. Rabbi Judah also told that they used to put two unfit loaves of the thank offering on the roof of the Temple portico, and as long as the loaves lay there, all the people would eat leavened foods. When they would remove one loaf, the people would keep leavened foods in suspense, neither eating nor burning it. And when they removed both loaves, the people began burning their leavened foods. Rabban Gamaliel taught that unconsecrated leavened bread (, chullin) could be eaten through the fourth hour of the morning, and leavened bread that was a heave-offering (, terumah) could be eaten through the fifth hour, and they burned them at the beginning of the sixth hour. The Mishnah taught that during the entire time that one was permitted to eat leavened food, one was allowed to feed it to cattle, beasts, and birds; sell it to a gentile; and otherwise to benefit from it.

And the Mishnah taught that they discharged their obligation even with unleavened bread made from agricultural produce for which it was uncertain whether tithes had been separated (, demai), with first tithe whose heave-offering had been separated, and with second tithe or consecrated materials that had been redeemed. And priests could discharge their obligation with unleavened bread made from the portion of dough that was given to priests (challah) and heave-offering (, terumah). But one could not discharge the obligation with unleavened bread made from grain that was mixed or untithed (tevel), nor with first tithe whose heave-offering had not been separated, nor with second tithe or consecrated materials that had not been
