The commandment of resting from work on the eighth day of Sukkot: To rest from any work which is not for the needs of food for the soul on the eighth day of the holiday of Sukkot, as it is stated (Leviticus 23:36), “on the eighth day, a holy occasion” — and that is the twenty-second day in Tishrei.

I have written above (Sefer HaChinukh 297) about the roots of the commandment of rest on the festival. And we will write more about the matter with God’s help in the prohibition of work on this day in this Order (Sefer HaChinukh 323). And there we will elucidate that this holiday is a holiday on its own.

And [it] is practiced in every place and at all times by males and females. And even though rest on the festival is from the positive commandments determined by time — since there is also the prohibition of a negative commandment in the doing of work, women are liable for it from the principle that is in our hands (Kiddushin 35a): “‘A man or a woman, if they do from any of the sins of a person’ (Numbers 5:6) — the verse equated a man and a woman for all of the punishments in the Torah.” And one who transgresses it and did work on this day has violated a positive commandment, besides that he violated a negative commandment, as we shall write in this Order (Sefer HaChinukh 323) with God’s help.
