סוכה א׳:ה׳ - א׳:ו׳

וחבילי זרדין – kind of reeds, and while they are still moist, animals eat them, and when they dry out, they are readied for kindling.

אין מסככין – when they are tied together, and not because they are invalid, but sometimes a person comes with his package on his shoulder and he raises and places it on the Sukkah to dry and he decides to use it as S’khakh/festive covering for the Sukkah, but the Torah stated, “you shall make/hold” (Deuteronomy 16:13) and not from what is already made, with that which is invalid, and this is not made even from the shade, but rather to dry out and it is already made with something invalid.

וכולן – those invalid things that we taught regarding the festive covering for the Sukkah.

כשרים לדפנות – that Sukkah implies the festive covering, but not the walls. Therefore, “After the ingathering from your threshing floor and your vat, you shall hold the Feast of Booths…’, the festive covering of the Sukkah is implied and not the walls.

מסככין בנסרים דברי ר' יהודה – with boards that have four [handbreadths] which is the measure of an important place, according to everyone, it is invalid. Less than three [handbreadths], everyone says, is valid, for it is considered like reeds. Where they disagree is from three until four. Rabbi Yehuda holds that since they lack the measurement of an important place, we should not make a decree lest a person sits underneath the ceiling of the house. But Rabbi Meir holds that since they go outside from the law of a legal fiction of considering separated parts as united, if the gap is less than three handbreadths, we make a decree lest a person should say, what does it matter to me with the S’khakh of these, what difference does it make if I sit under the ceiling of my house. But the Halakha is according to Rabbi Yehuda.
