Leviticus 23:9-21 And the Lord spoke to Moses, saying:

DouayRheims⁽ⁱ⁾ ⁹ And the Lord spoke to Moses, saying: ¹⁰ Speak to the children of Israel, and thou shalt say to them: When you shall have entered into the land which I will give you, and shall reap your corn, you shall bring sheaves of ears, the firstfruits of your harvest to the priest. ¹¹ Who shall lift up the sheaf before the Lord, the next day after the sabbath, that it may be acceptable for you, and shall sanctify it. ¹² And on the same day that the sheaf is consecrated, a lamb without blemish of the first year shall be killed for a holocaust of the Lord. ¹³ And the libations shall be offered with it: two tenths of flour tempered with oil, for a burnt offering of the Lord, and a most sweet odour. Libations also of wine, the fourth part of a hin. ¹⁴ You shall not eat either bread, or parched corn, or frumenty or the harvest, until the day that you shall offer thereof to your God. It is a precept for ever throughout your generations, and all your dwellings. ¹⁵ You shall count therefore from the morrow after the sabbath, wherein you offered the sheaf of firstfruits, seven full weeks. ¹⁶ Even unto the morrow after the seventh week be expired, that is to say, fifty days: and so you shall offer a new sacrifice to the Lord. ¹⁷ Out of all your dwellings, two loaves of the firstfruits, of two tenths of flour leavened, which you shall bake for the firstfruits of the Lord. ¹⁸ And you shall offer with the loaves seven lambs without blemish of the first year, and one calf from the herd, and they shall be for a holocaust with their two rams: and they shall be for a holocaust with their libations for a most sweet odour to the Lord. ¹⁹ You shall offer also a buck goat for sin, and two lambs of the first year for sacrifices of peace offerings. ²⁰ And when the priest hath lifted them up with the loaves of the firstfruits before the Lord, they shall fall to his use. ²¹ And you shall call this day most solemn, and most holy. You shall do no servile work therein. It shall be an everlasting ordinance in all your dwellings and generations.
