(16) and the Feast of the Harvest, of the first fruits of your work, of what you sow in the field; and the Feast of Ingathering at the end of the year, when you gather in the results of your work from the field.

(22) You shall observe the Feast of Weeks, of the first fruits of the wheat harvest; and the Feast of Ingathering at the turn of the year.

(4) These are the set times of the LORD, the sacred occasions, which you shall celebrate each at its appointed time: (5) In the first month, on the fourteenth day of the month, at twilight, there shall be a passover offering to the LORD, (6) and on the fifteenth day of that month the LORD’s Feast of Unleavened Bread. You shall eat unleavened bread for seven days. (7) On the first day you shall celebrate a sacred occasion: you shall not work at your occupations. (8) 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. (9) The LORD spoke to Moses, saying: (10) 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. (11) He shall elevate the sheaf before the LORD for acceptance in your behalf; the priest shall elevate it on the day after the sabbath. (12) 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. (13) 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. (14) 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. (15) 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: (16) you must count until the day after the seventh week—fifty days; then you shall bring an offering of new grain to the LORD. (17) 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. (18) 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. (19) You shall also offer one he-goat as a sin offering and two yearling lambs as a sacrifice of well-being. (20) 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. (21) 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. (22) 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.

(26) On the day of the first fruits, your Feast of Weeks, when you bring an offering of new grain to the LORD, you shall observe a sacred occasion: you shall not work at your occupations. (27) You shall present a burnt offering of pleasing odor to the LORD: two bulls of the herd, one ram, seven yearling lambs. (28) The meal offering with them shall be of choice flour with oil mixed in, three-tenths of a measure for a bull, two-tenths for a ram, (29) and one-tenth for each of the seven lambs. (30) And there shall be one goat for expiation in your behalf. (31) You shall present them—see that they are without blemish—with their libations, in addition to the regular burnt offering and its meal offering.

(9) You shall count off seven weeks; start to count the seven weeks when the sickle is first put to the standing grain. (10) Then you shall observe the Feast of Weeks for the LORD your God, offering your freewill contribution according as the LORD your God has blessed you. (11) You shall rejoice before the LORD your God with your son and daughter, your male and female slave, the Levite in your communities, and the stranger, the fatherless, and the widow in your midst, at the place where the LORD your God will choose to establish His name. (12) Bear in mind that you were slaves in Egypt, and take care to obey these laws.

(1) When you enter the land that the LORD your God is giving you as a heritage, and you possess it and settle in it, (2) you shall take some of every first fruit of the soil, which you harvest from the land that the LORD your God is giving you, put it in a basket and go to the place where the LORD your God will choose to establish His name. (3) You shall go to the priest in charge at that time and say to him, “I acknowledge this day before the LORD your God that I have entered the land that the LORD swore to our fathers to assign us.” (4) The priest shall take the basket from your hand and set it down in front of the altar of the LORD your God. (5) You shall then recite as follows before the LORD your God: “My father was a fugitive Aramean. He went down to Egypt with meager numbers and sojourned there; but there he became a great and very populous nation. (6) The Egyptians dealt harshly with us and oppressed us; they imposed heavy labor upon us. (7) We cried to the LORD, the God of our fathers, and the LORD heard our plea and saw our plight, our misery, and our oppression. (8) The LORD freed us from Egypt by a mighty hand, by an outstretched arm and awesome power, and by signs and portents. (9) He brought us to this place and gave us this land, a land flowing with milk and honey. (10) Wherefore I now bring the first fruits of the soil which You, O LORD, have given me.” You shall leave it before the LORD your God and bow low before the LORD your God. (11) And you shall enjoy, together with the Levite and the stranger in your midst, all the bounty that the LORD your God has bestowed upon you and your household.
