Leviticus 23:1-23:22
The Lord spoke to Moses, saying: Speak to the Israelite people and say to them:
These are My fixed times, the fixed times of the Lord, which you shall proclaim as sacred occasions.
On six days work may be done, but on the seventh day there shall be a sabbath of complete rest, a sacred occasion. You shall do no work; it shall be a sabbath of the Lord throughout your settlements.
These are the set times of the Lord, the sacred occasions, which you shall celebrate each at its appointed time: In the first month, on the fourteenth day of the month, at twilight, there shall be a passover offering to the Lord, and on the fifteenth day of that month the Lord's Feast of Unleavened Bread. You shall eat unleavened bread for seven days. On the first day you shall celebrate a sacred occasion: you shall not work at your occupations. Seven days you shall make offerings by fire to the Lord. The seventh day shall be a sacred occasion: you shall not work at your occupations.
The Lord spoke to Moses, saying: Speak to the Israelite people and say to them:
When you enter the land that I am giving to you and you reap its harvest, you shall bring the first sheaf of your harvest to the priest. He shall elevate the sheaf before the Lord for acceptance in your behalf; the priest shall elevate it on the day after the sabbath. On the day that you elevate the sheaf, you shall offer as a burnt offering to the Lord a lamb of the first year without blemish. The meal offering with it shall be two-tenths of a measure of choice flour with oil mixed in, an offering by fire of pleasing odor to the Lord; and the libation with it shall be of wine, a quarter of a hin. Until that very day, until you have brought the offering of your God, you shall eat no bread or parched grain or fresh ears; it is a law for all time throughout the ages in all your settlements.
And from the day on which you bring the sheaf of elevation offering--the day after the sabbath--you shall count off seven weeks. They must be complete: you must count until the day after the seventh week--fifty days; then you shall bring an offering of new grain to the Lord. You shall bring from your settlements two loaves of bread as an elevation offering; each shall be made of two-tenths of a measure of choice flour, baked after leavening, as first fruits to the Lord. With the bread you shall present, as burnt offerings to the Lord, seven yearling lambs without blemish, one bull of the herd, and two rams, with their meal offerings and libations, an offering by fire of pleasing odor to the Lord. You shall also offer one he-goat as a sin offering and two yearling lambs as a sacrifice of well-being.
The priest shall elevate these--the two lambs--together with the bread of first fruits as an elevation offering before the Lord; they shall be holy to the Lord, for the priest. On that same day you shall hold a celebration; it shall be a sacred occasion for you; you shall not work at your occupations. This is a law for all time in all your settlements, throughout the ages.
And when you reap the harvest of your land, you shall not reap all the way to the edges of your field, or gather the gleanings of your harvest; you shall leave them for the poor and the stranger: I the Lord am your God.
