Commentary for Sukkah 3:14
רַבִּי יוֹסֵי אוֹמֵר, יוֹם טוֹב הָרִאשׁוֹן שֶׁל חָג שֶׁחָל לִהְיוֹת בְּשַׁבָּת, וְשָׁכַח וְהוֹצִיא אֶת הַלּוּלָב לִרְשׁוּת הָרַבִּים, פָּטוּר, מִפְּנֵי שֶׁהוֹצִיאוֹ בִרְשׁוּת:
R. Yossi says: If the first day of the festival fell out on Shabbath, and he forgot and took out his lulav to the public domain, he is not liable (for a sin-offering), having taken it out under (Torah) sanction. [This, in an instance where he had not yet fulfilled his obligation of taking the lulav at the time he took it out. But if he had fulfilled his obligation beforehand, he is liable, not being occupied thenceforward in the performance of a mitzvah. But how is it possible that he had not fulfilled his obligation before he took it out? Had he not fulfilled it (automatically) the very moment he picked it up! (The answer:) Such an instance does obtain if he inverted it; for a man has not fulfilled his obligation in respect to all mitzvoth (of this kind) unless he performs them (handling them, e.g., lulav, hadas), in the direction of their growth, viz. (Exodus 26:15): "standing shittim wood" — standing in the direction of their growth. Or else, (the instance is one in which) he took it out in a vessel. For taking it "demeaningly" through something else is not called "taking." The halachah is in accordance with R. Yossi.]
