Leviticus 23:26-28

King James Version

²⁶ And the Lord spake unto Moses, saying,

²⁷ Also on the tenth day of this seventh month there shall be a day of atonement: it shall be an holy convocation unto you; and ye shall afflict your souls, and offer an offering made by fire unto the Lord.

²⁸ And ye shall do no work in that same day: for it is a day of atonement, to make an atonement for you before the Lord your God.
