Leviticus 23:23-27

23Again the Lord spoke to Moses, saying, 24“Speak to the sons of Israel, saying, ‘1In the seventh month on the first of the month you shall have a 2rest, a 3reminder by blowing of trumpets, a holy convocation. 25You shall 4not do any laborious work, but you shall present an offering by fire to the Lord.’”

26The Lord spoke to Moses, saying, 27“On exactly 5the tenth day of this seventh month is 6the day of atonement; it shall be a holy convocation for you, and you shall humble your souls and present an offering by fire to the Lord.
