Leviticus 23:12

10“Speak to the children of Israel, and tell them, ‘When you have come into the land which I give to you, and shall reap its harvest, then you shall bring the sheaf of the first fruits of your harvest to the priest.

11He shall wave the sheaf before the LORD, to be accepted for you. On the next day after the Sabbath the priest shall wave it.

12On the day when you wave the sheaf, you shall offer a male lamb without defect a year old for a burnt offering to the LORD.

13The meal offering with it shall be two tenths of an ephah of fine flour mixed with oil, an offering made by fire to the LORD for a pleasant aroma; and the drink offering with it shall be of wine, the fourth part of a hin.

14You must not eat bread, or roasted grain, or fresh grain, until this same day, until you have brought the offering of your God. This is a statute forever throughout your generations in all your dwellings.
