Leviticus 23:27

²⁷In the tenth day of this seventh month, the day of cleansings shall be most solemn, and it shall be called holy; and ye shall torment your souls to God, and ye shall offer burnt sacrifice to the Lord; (And on the tenth day of this seventh month, shall be the most solemn Day of Cleansing, or the Day of Atonement, and there shall be a holy gathering; and ye shall torment your souls before God, and ye shall offer a burnt sacrifice to the Lord;)
