Exodus 35,1. “these are the things that the Lord commanded to be done. For six days work shall be performed, etc.” Our sages in Shabbat 70 see in the numerical value of the letters in the word: אלה i.e. 39, an allusion to the 39 categories of “work” prohibited to be performed by Israelites on the Sabbath. These categories of work are understood as especially mundane in nature, the Ari z’al pointing out that when the prophet Jeremiah (Lamentations 1,16) says: על אלה אני בוכיה, “on account of these things I weep,” he meant that violation of these prohibited activities of the Sabbath require the Jewish people to collectively rehabilitate themselves by a special activity, מלאכה, and this is why the positive instruction לעשות, “to perform,” [and not as “to desist from” Ed.] has been added.
