27“The tenth day of this seventh month is the Day of Atonement. You shall hold a sacred assembly and humble yourselves, and present an offering made by fire to the LORD.
28On this day you are not to do any work, for it is the Day of Atonement, when atonement is made for you before the LORD your God.
29If anyone does not humble himself on this day, he must be cut off from his people.
— Leviticus 23:27-29
