Leviticus 23:21-27

²¹And ye shall make proclamation on the selfsame day; there shall be a holy convocation unto you; ye shall do no manner of servile work; it is a statute for ever in all your dwellings throughout your generations.

²²And when ye reap the harvest of your land, thou shalt not wholly reap the corner of thy field, neither shalt thou gather the gleaning of thy harvest; thou shalt leave them for the poor, and for the stranger: I am the LORD your God.

²³And the LORD spoke unto Moses, saying:

²⁴Speak unto the children of Israel, saying: In the seventh month, in the first day of the month, shall be a solemn rest unto you, a memorial proclaimed with the blast of horns, a holy convocation.

²⁵Ye shall do no manner of servile work; and ye shall bring an offering made by fire unto the LORD.

²⁶And the LORD spoke unto Moses, saying:

²⁷Howbeit on the tenth day of this seventh month is the day of atonement; there shall be a holy convocation unto you, and ye shall afflict your souls; and ye shall bring an offering made by fire unto the LORD.
