The LORD said to Moses, "The tenth of this seventh month is the Day of Atonement, when you shall hold a sacred assembly and mortify yourselves and offer an oblation to the LORD. On this day you shall not do any work, because it is the Day of Atonement, when atonement is made for you before the LORD, your God. Anyone who does not mortify himself on this day shall be cut off from his people, and if anyone does any work on this day, I will remove him from the midst of his people. This is a perpetual statute for you and your descendants wherever you dwell: you shall do no work, but shall keep a sabbath of complete rest and mortify yourselves. Beginning on the evening of the ninth of the month, you shall keep this sabbath of yours from evening to evening."
Leviticus 23:26-32
