Leviticus 23:4-14

⁴ 'These are the feasts of the Lord, holy convocations which you shall proclaim at their appointed times ⁵ On the fourteenth day of the first month at twilight is the Lord's Passover. ⁶ And on the fifteenth day of the same month is the Feast of Unleavened Bread to the Lord; seven days you must eat unleavened bread. ⁷ On the first day you shall have a holy convocation; you shall do no customary work on it. ⁸ But you shall offer an offering made by fire to the Lord for seven days. The seventh day shall be a holy convocation; you shall do no customary work on it.' " ⁹ And the Lord spoke to Moses, saying, ¹⁰ "Speak to the children of Israel, and say to them: 'When you come into the land which I give to you, and reap its harvest, then you shall bring a sheaf of the firstfruits of your harvest to the priest. ¹¹ He shall wave the sheaf before the Lord, to be accepted on your behalf; on the day after the Sabbath the priest shall wave it. ¹² And you shall offer on that day, when you wave the sheaf, a male lamb of the first year, without blemish, as a burnt offering to the Lord. ¹³ Its grain offering shall be two-tenths of an ephah of fine flour mixed with oil, an offering made by fire to the Lord, for a sweet aroma; and its drink offering shall be of wine, one-fourth of a hin. ¹⁴ You shall eat neither bread nor parched grain nor fresh grain until the same day that you have brought an offering to your God; it shall be a statute forever throughout your generations in all your dwellings
