Peah 6:3 - 6:4

ראשי שורות העומר שכנגדו מוכיח – Nearby ahead, it explains this (Tractate Peah, Chapter 6, Mishnah 4).

שנים שהתחילו מאמצע שורה – of sheaves, this one turned his face to the north and that one turned his face to the south.

ושכחו לפניהם – after they had started to bind and pile the sheaves, they skipped and forgot it, that is forgetting, as we call it (Deuteronomy 24:19): “Do not turn back to get it.”

ולאחריהם אינו שכחה – if when they turned their faces – this one to the north and that one to the south, and they began to bind and pile the sheaves, and there remained one sheaf between them that they had forgotten, that is not forgetting, because both of them relied upon each upon the other and through that it was forgotten.

יחיד שהתחיל מראש השורה – Now it explains to that which is taught in the Mishnah above (Tractate Peah, Chapter 6, Mishnah 3), [as regards a sheaf at] the end of the row, [the presence of] a sheaf at the end of the row across from it proves [that the first sheaf has not been forgotten], such as there are ten rows here of ten by ten Omers set up by rows from the north to the south, and he began to bind and pile the sheaves at the end of one row and he forgot an Omer behind it, that is forgetting, since he passed it and an Omer stands near it, we call that (Deuteronomy 24:19): “Do not turn back to get it.” Bu if he forgot one Omer/sheaf or two at the end of the row, that is in front of him, and he placed them and return and began to bind and pile the sheaves from the beginning of the second row, that is not forgetting, for we don’t call it “Do not turn back” (ibid.), for I saw that it is his intention to work on another row from those which he left from east to west, and that is what is taught in the Mishnah (in Tractate Peah, Chapter 6, Mishnah 3), at the end of the row across from it proves the point, for the Omer sheaves of the other rows prove concerning those which he left that they were not forgotten and are fit to be considered with them in another row.
