There is so much beautiful symbolism in the holiday of Sukkot. One of my favorites is derived from a teaching on the top of today’s daf.
Yesterday, when determining how many corners (horns) the priest needed to sprinkle the blood of sacrifice upon, there was an argument made that if a word was written in the plural it must symbolize at least two. It gets us to a funny place where one could read that a sukkah needs 6 sides . . .
The Gemara raises another objection to this method of exposition: If that is so, consider the case of a sukka, about which it is stated: “In sukkot [basukkot] shall you reside seven days; all that are homeborn in Israel shall reside in sukkot [basukkot]. So that your future generations will know that I caused the children of Israel to reside in sukkot [basukkot] when I took them out of the land of Egypt: I am the Lord your God” (Leviticus 23:42–43). Two instances of the word basukkot are written in a deficient manner, i.e., without a vav, indicating the singular, and one instance is written in plene form, i.e., with a vav, indicating the plural form. The Sages derived from here that a sukka must have four walls. Why not say that the vocalized text, read in the plural, is effective, requiring six walls, and likewise, the consonantal text, read in the singular, is effective, requiring four walls, and therefore one should be required to build a sukka with five walls?
On today’s daf the number of walls necessary is reduced to what we require today:
The Gemara answers: There, one of the five indicated by the verse is needed entirely for the mitzva itself, i.e., to teach the basic halakha that one must dwell in a sukka. And another one of the five is needed to teach that a sukka, as is indicated by its name, must have a covering [sekhakha]. Accordingly, there are three left, alluding to the requirement that a sukka must have three walls. The Gemara adds that the halakha transmitted to Moses from Sinai comes and reduces the size of the third wall, teaching that it need not be complete, and sets its minimum length at only one handbreadth.
So, the walls required for a sukkah to be kosher are two walls plus a handsbreadth. Now, the reason this is my favorite piece of symbolism on the holiday.
Take a look at any of your arms, says Rabbi Isaac Luria, and you will notice its division into three distinct sections. The first is from the shoulder to the elbow; the second is from the elbow to the wrist; and the handsbreadth is represented by our hand. When we sit in the sukkah, it is as if we are being hugged by God.
On Rosh Hashanah and Yom Kippur we are judged, we repent, we vow to do better. Then, God takes us into God’s embrace, and we dwell for an entire week in the sukkah, God’s hug.
