이는 너희의 쉴 안식일이라 너희는 스스로 괴롭게 하고 이 달 구일 저녁 곧 그 저녁부터 이튿날 저녁까지 안식을 지킬지니라
Sefer HaMitzvot
That is that He commanded us to rest from work and [certain] actions on Yom Kippur. And that is His, may He be exalted, saying, "It is a Shabbat of Shabbaton for you" (Leviticus 16:31). And we have already explained several times that this rest is a positive commandment. (See Parashat Emor; Mishneh Torah, Rest on a Holiday 1.)
