Leviticus 23:9-14

⁹Then the Lord spoke to Moses, saying, ¹⁰“Speak to the sons of Israel and say to them, ‘When you enter the land which I am going to give to you and reap its harvest, then you shall bring in the sheaf of the first fruits of your harvest to the priest. ¹¹He shall wave the sheaf before the Lord for you to be accepted; on the day after the sabbath the priest shall wave it. ¹²Now on the day when you wave the sheaf, you shall offer a male lamb one year old without defect for a burnt offering to the Lord. ¹³Its grain offering shall then be two-tenths of an ephah of fine flour mixed with oil, an offering by fire to the Lord for a soothing aroma, with its drink offering, a fourth of a hin of wine. ¹⁴Until this same day, until you have brought in the offering of your God, you shall eat neither bread nor roasted grain nor new growth. It is to be a perpetual statute throughout your generations in all your dwelling places.
