Leviticus 23:22-31

²²And when you reap the corn of your land, you shall not cut it to the very ground: neither shall you gather the ears that remain; but you shall leave them for the poor and for the strangers. I am the Lord your God.

²³And the Lord spoke to Moses, saying:

²⁴Say to the children of Israel: The seventh month, on the first day of the month, you shall keep a sabbath, a memorial, with she sound of trumpets, and it shall be called holy.

²⁵You shall do no servile work therein, and you shall offer a holocaust to the Lord.

²⁶And the Lord spoke to Moses, saying:

²⁷Upon the tenth day of this seventh month shall be the day of atonement, it shall be most solemn, and shall be called holy: and you shall afflict your souls on that day, and shall offer a holocaust to the Lord.

²⁸You shall do no servile work in the time of this day: because it is a day of propitiation, that the Lord your God may be merciful unto you.

²⁹Every soul that is not afflicted on this day, shall perish from among his people:

³⁰And every soul that shall do any work, the same will I destroy from among his people.

³¹You shall do no work therefore on that day: it shall be an everlasting ordinance unto you in all your generations, and dwellings.
