Mishnayos Peah Perek 6 Mishnah 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.

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.

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.
