Leviticus 23:1-14

And the LORD spoke to Moses, saying, “Speak to the children of Israel, and say to them: ‘The feasts of the LORD, which you shall proclaim to be holy convocations, these are My feasts. ‘Six days shall work be done, but the seventh day is a Sabbath of solemn rest, a holy convocation. You shall do no work on it; it is the Sabbath of the LORD in all your dwellings. ‘These are the feasts of the LORD, holy convocations which you shall proclaim at their appointed times. On the fourteenth day of the first month at twilight is the LORD’s Passover. 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. On the first day you shall have a holy convocation; you shall do no customary work on it. 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.’ ” And the LORD spoke to Moses, saying, “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. 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. 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. 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. 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.
