Leviticus 23:10-14

¹⁰“Tell the Israelites that when you enter the land that I'm giving you and you harvest your crops, take a stack of grain from the firstfruits of your harvest to the priest.

¹¹He will wave the stack of grain before the Lord so that it may be accepted on your behalf. The priest is to do this the day following the Sabbath.

¹²When you wave the stack of grain, you are to present a one-year-old lamb without defects as a burnt offering to the Lord,

¹³together with its grain offering of two-tenths of an ephah of best flour mixed with olive oil (a food offering to the Lord to be accepted by him) and its drink offering of a quarter of a hin of wine.

¹⁴Don't eat any bread, roasted grain, or new grain until the time you bring this offering to your God. This regulation is for all time and for future generations everywhere you live.
