יג כמאן אזלא הא דתניא לולב מצוה לאוגדו ואם לא אגדו כשר אי ר' יהודה כי לא אגדו אמאי כשר אי רבנן אמאי מצוה לעולם רבנן היא ומשום שנאמר (שמות טו, ב) זה אלי ואנוהו התנאה לפניו במצות:
13 According to whom is that which has been taught: It is a mitzvah to tie [the components of] the lulav together, but if one did not tie them, it is [still] valid? If it is according to R. Judah, why is it valid if one does not tie them. and if it is according to the Sages, why is it ‘mitzvah'? It is in fact according to the Rabbis, but [it is a mitzvah] since it is written, "This is my God and I will adorn Him" (Exodus 15:2) be adorned before Him in [the due performance of] religious duties.
