Leviticus 23:10-14

10Speak unto the children of Israel, and say unto them, When ye are come into the land which I give unto you, and shall reap the harvest thereof, then ye shall bring the sheaf of the first-fruits of your harvest unto the priest: 11and he shall wave the sheaf before Jehovah, to be accepted for you: on the morrow after the sabbath the priest shall wave it. 12And in the day when ye wave the sheaf, ye shall offer a he-lamb without blemish a year old for a burnt-offering unto Jehovah. 13And the meal-offering thereof shall be two tenth parts of an ephah of fine flour mingled with oil, an offering made by fire unto Jehovah for a sweet savor; and the drink-offering thereof shall be of wine, the fourth part of a hin. 14And ye shall eat neither bread, nor parched grain, nor fresh ears, until this selfsame day, until ye have brought the oblation of your God: it is a statute for ever throughout your generations in all your dwellings.
