Leviticus 23:15-32

‘You shall count from the day after the Sabbath, from the day when you brought in the sheaf (tied bundle of grain) of the wave offering; there shall be seven complete Sabbaths (seven full weeks). You shall count fifty days to the day after the seventh Sabbath; then you shall present a new grain offering to the LORD. You shall bring in from your places two loaves of bread as a wave offering, made from two-tenths of an ephah of fine flour; they shall be baked with leaven as first fruits to the LORD. And you shall offer with the bread seven unblemished lambs, one year old, and one young bull and two rams. They are to be a burnt offering to the LORD, with their grain offering and their drink offerings. It is an offering by fire, a sweet and soothing aroma to the LORD. And you shall sacrifice one male goat as a sin offering and two male lambs, one year old as a sacrifice of peace offerings. The priest shall wave them before the LORD as a wave offering, together with the bread of the first fruits and the two lambs. They are to be holy to the LORD for the priest. On this same day you shall make a proclamation, you are to have a holy convocation (calling together); you shall not do any laborious work [on that day]. It is to be a permanent statute throughout your generations wherever you may be. ‘When you reap the harvest of your land, you shall not reap to the edges of your field, nor gather the gleaning of your harvest; you are to leave them for the poor and for the stranger. I am the LORD your God.’ ” Again the LORD spoke to Moses, saying, “Say to the children of Israel, ‘On the first day of the seventh month (almost October), you shall observe a day of solemn sabbatical rest, a memorial day announced by the blowing of trumpets, a holy convocation. You shall not do any laborious work [on that day], but you shall present an offering by fire to the LORD.’ ” The LORD spoke to Moses, saying, “Also the tenth day of this seventh month is the Day of Atonement; it shall be a holy convocation for you, and you shall humble yourselves [by fasting] and present an offering by fire to the LORD. You shall not do any work on this same day, for it is the Day of Atonement, to make atonement on your behalf before the LORD your God. If there is any person who will not humble himself on this same day, he shall be cut off from his people [excluding him from the atonement made for them]. If there is any person who does any work on this same day, I will destroy that person from among his people. You shall do no work at all [on that day]. It is a permanent statute throughout your generations wherever you may be. It is to be to you a Sabbath of complete rest, and you shall humble yourselves. On the ninth day of the month at evening, from evening to evening you shall keep your Sabbath.”
