Leviticus 23:26-32

The LORD said to Moses, “The Day of Cleansing will be on the tenth day of the seventh month. There will be a holy meeting, and you will deny yourselves and bring an offering made by fire to the LORD. Do not do any work on that day, because it is the Day of Cleansing. On that day the priests will go before the LORD and perform the acts to make you clean from sin so you will belong to the LORD. “Anyone who refuses to give up food on this day must be cut off from the people. If anyone works on this day, I will destroy that person from among the people. You must not do any work at all; this law will continue for people from now on wherever you live. It will be a special day of rest for you, and you must deny yourselves. You will start this special day of rest on the evening after the ninth day of the month, and it will continue from that evening until the next evening.”
