Leviticus 23:10-14

“Speak to the children of Israel and say to them, ‘When you enter the land which I am giving you and reap its harvest, you shall bring the sheaf of the first fruits of your harvest to the priest. He shall wave the sheaf before the LORD so that you may be accepted; the priest shall wave it on the day after the Sabbath. Now on the day when you wave the sheaf you shall offer a male lamb one year old without blemish as a burnt offering to the LORD. Its grain offering shall be two-tenths of an ephah of fine flour mixed with [olive] oil, an offering by fire to the LORD for a sweet and soothing aroma, with its drink offering [to be poured out], a fourth of a hin of wine. You shall not eat any bread or roasted grain or new growth, until this same day when you bring in the offering to your God; it is a permanent statute throughout your generations wherever you may be.
