Leviticus 23:13

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.

15 You shall count to you from the next day after the Sabbath, from the day that you brought the sheaf of the wave-offering; seven Sabbaths shall there be complete:

16 even to the next day after the seventh Sabbath shall you number fifty days; and you shall offer a new meal-offering to Yahweh.
