Leviticus 23:25-32

²⁵ye shall not do any servile work therein, and ye shall offer burnt sacrifice to the Lord.

²⁶And the Lord spake to Moses, and said,

²⁷In the tenth day of this seventh month, the day of cleansings or purging 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;

²⁸ye shall not do any work in the time of this day, for it is the day of cleansing, that your Lord God be merciful to you.

²⁹Each man which is not tormented in this day, shall perish from his peoples,

³⁰and I shall do away from his people that man that doeth anything of work in that day;

³¹therefore ye shall not do anything of work in that day; it shall be a lawful thing everlasting to you in all your generations and dwellings;

³²it is the sabbath of resting. Ye shall therein torment your souls from the ninth day of the month; from the eventide till to eventide ye shall hallow your sabbaths.
