These are the things that the L-rd has commanded you to do (Ex. 35:1)
Why is the plural “things” used, when what followed was only one commandment, the mitzva to keep Shabbat? These “things” refers to the 39 categories of creative work that are forbidden on Shabbat. During the week, a Jew’s service consists of elevating and refining the material world by engaging in these tasks. On Shabbat, his service is to refrain from them, thereby completing the process of elevation. The mitzva of Shabbat thus contains all of the Torah’s mitzvot within it, the underlying purpose of which is to elevate the physical realm and make it spiritual.
(Ohr HaTorah)
You shall not kindle any fire throughout your habitations (Ex. 35:3)
The main reason we observe Shabbat is in remembrance of the Six Days of Creation. As fire was not created until after the first Shabbat ended, the Torah specifically singles it out - lest anyone think it isn’t included in the 39 prohibited labors.
(Rabbi Yonatan Eibeschutz)
They came, the men with the women, whoever was generous of heart, and every man who waved a wave offering of gold unto G-d (Ex. 35:22)
The Jews were so eager to make donations to the Sanctuary that they didn’t stop to calculate the amount of gold they were contributing. Rather, they “waved it about” and gave with an open hand, like a rich benefactor who disburses his charity liberally.
(Be’er Mayim Chaim)
