Leviticus 23:9-16

9The Lord spoke to Moses:

10“Speak to the Israelites and tell them, ‘When you enter the land that I am about to give to you and you gather in its harvest, then you must bring the sheaf of the first portion of your harvest to the priest,

11and he must wave the sheaf before the Lord to be accepted for your benefit – on the day after the Sabbath the priest is to wave it.

12On the day you wave the sheaf you must also offer a flawless yearling lamb for a burnt offering to the Lord,

13along with its grain offering, two tenths of an ephah of choice wheat flour mixed with olive oil, as a gift to the Lord, a soothing aroma, and its drink offering, one fourth of a hin of wine.

14You must not eat bread, roasted grain, or fresh grain until this very day, until you bring the offering of your God. This is a perpetual statute throughout your generations in all the places where you live.

15“‘You must count for yourselves seven weeks from the day after the Sabbath, from the day you bring the wave offering sheaf; they must be complete weeks.

16You must count fifty days – until the day after the seventh Sabbath – and then you must present a new grain offering to the Lord.
