Leviticus 23:10–17

¹⁰“Speak to the Israelites and say to them: When you enter the land that I am giving you and you reap its harvest, you shall bring the sheaf of the first fruits of your harvest to the priest.^{* 11}He shall raise the sheaf before the Lord, that you may find acceptance; on the day after the Sabbath the priest shall raise it. ¹²On the day when you raise the sheaf, you shall offer a lamb a year old, without blemish, as a burnt offering to the Lord. ¹³And the grain offering with it shall be two-tenths of an ephah of choice flour mixed with oil, an offering by fire^t of pleasing odor to the Lord, and the drink offering with it shall be of wine, one-fourth of a hin.^{* 14}You shall eat no bread or parched grain or fresh ears until that very day, until you have brought the offering of your God. This is a statute forever throughout your generations in all your settlements.

The Festival of Weeks

¹⁵“And from the day after the Sabbath, from the day on which you bring the sheaf of the elevation offering, you shall count seven full weeks.^{* 16}You shall count until the day after the seventh Sabbath, fifty days; then you shall present an offering of new grain to the Lord.^{* 17}You shall bring from your settlements two loaves of bread as an elevation offering, each made of two-tenths of an ephah; they shall be of choice flour, baked with leaven, as first fruits to the Lord.^*
