We may reap the irrigated fields in the valleys, but we may not stack. The people of Jericho reaped with the approval of the Sages and stacked against the Sages’ wishes, but the Sages did not issue a protest against them. One may reap unripe grain and feed it to animals. Said R’ Yehudah: When? When he began before it reached a third. R’ Shimon says: He may reap and feed [it] even after it has reached a third.

The commandment of the omer is that it should come from standing grain; if he did not find, he may bring from the sheaves. Its commandment is that it come from the fresh; if he did not find, he may bring from the dry. Its commandment is that it be reaped by night; if it is reaped by day it is valid. And it overrides the Sabbath.
