Leviticus 23:10

7 In the first day ye shall have a holy convocation: ye shall do no servile work.

8 But ye shall offer an offering made by fire unto Jehovah seven days: in the seventh day is a holy convocation; ye shall do no servile work.

9 And Jehovah spake unto Moses, saying,

10 Speak 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:

11 and he shall wave the sheaf before Jehovah, to be accepted for you: on the morrow after the sabbath the priest shall wave it.

12 And 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.

13 And 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.
