Leviticus 23:11

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

9 Yahweh spoke to Moses, saying,

10 Speak to the children of Israel, and tell them, When you are come into the land which I give to you, and shall reap the harvest of it, then you shall bring the sheaf of the first-fruits of your harvest to the priest:

11 and he shall wave the sheaf before Yahweh, to be accepted for you: on the next day after the Sabbath the priest shall wave it.

12 In the day when you wave the sheaf, you shall offer a he-lamb without blemish a year old for a burnt offering to Yahweh.

13 The meal-offering of it shall be two tenth parts [of an ephah] of fine flour mingled with oil, an offering made by fire to Yahweh for a sweet savor; and the drink-offering of it shall be of wine, the fourth part of a hin.

14 You shall eat neither bread, nor parched grain, nor fresh ears, until this same day, until you have brought the offering of your God: it is a statute forever throughout your generations in all your dwellings.
