Komentarz do Pea 6:7

קמה שיש בה סאתים ושכחה אינו שכחה – since we derived the forgotten standing crop from the forgotten Omer. Just as an Omer which contains two Se’ah is not forgotten, so also the standing crop which has two Se’ah is not forgotten, and the forgotten standing crop we derive it from the Biblical verse, as it is written (Deuteronomy 24:19): “[When you reap the harvest in your field] and overlook a sheaf in the field,” to include the forgotten standing crop.

Introduction In today’s mishnah we see that the rabbis extended the laws of forgotten sheaves to standing stalks of grain as well. The question then is, when is a stalk considered to have been forgotten?

טופח – a kind of very thin pulse, and we call it in Arabic “Gilba’an.” But in the standing barley grain, we are speaking of when they were emptied of grain/blasted and they became thin like an inferior kind of barley, and even so, we see them as if they are thick like the rest of the barley, and if when we consider them thick like other barley, there would be in them two Se’ah, even though that now they are blasted and don’t have two Se’ah, they are not forgotten. And we should not interpret that of the inferior barley explicitly that they should consider it as if they are like thick barley, but with barley that was blasted and became inferior, and this is what we say in the Jerusalem Talmud, we see the blasted [barley] as if they are full.

A standing stalk of grain that contains two seahs and he forgot it, it is not considered “forgotten.” Truth be told, I’m not really sure that one stalk of grain can actually produce two seahs of grain, but if it could, it would not be considered forgotten, just as a sheaf with two seahs is not considered forgotten.

ענוה של שעורים – the word ענוה /fertility with [the letter] ו' (Vav), like [the word] ענבה /stalk of grapes with a ב' (Bet), that is to say, a grain/berry of barley.

If it does not contain two seahs now, but is fit to yield two seahs, even if it was of an inferior kind of barley, it is regarded as full barley [grains]. If the stalk will yield two seahs, then we treat it as if it has two seahs and it is not considered forgotten. Indeed, this makes a lot of sense because if this stalk was going to produce a whole two seahs of grain, he probably left it in the field so that he could harvest it when it ripened. The mishnah adds that even if the barley was low quality barley such that it would not actually yield two seahs, we evaluate it as if each grain was of full barley and if the amount that this type of barley will yield equals two seahs, then it is not forgotten.
