The 165th mitzvah is that we are commanded to refrain from the various categories of melachah1 and prohibited activities2 on this day [of Yom Kippur]
The source of this commandment is G‑d's statement,3 "It is a Sabbath of Sabbaths to you."
We have already explained many times4 that the term Shabbason indicates a positive commandment.5
See first footnote in N320.
Kapach, 5731, footnote 23 points out that the Arabic word, "ashgal" refers in this context to all other types of prohibited activity.
Lev. 16:31.
See P90, P135, P159, and P163.
Since this mitzvah prohibits melachah, it would seem to be a negative commandment. However, since the term "Shabbason" is used, the mitzvah is counted among the positive commandments.
