Leviticus 23:7-16

7On the first day hold a sacred assembly and do no regular work. 8For seven days present a food offering to the Lord. And on the seventh day hold a sacred assembly and do no regular work.’ ” 9The Lord said to Moses, 10“Speak to the Israelites and say to them: ‘When you enter the land I am going to give you and you reap its harvest, bring to the priest a sheaf of the first grain you harvest. 11He is to wave the sheaf before the Lord so it will be accepted on your behalf; the priest is to wave it on the day after the Sabbath. 12On the day you wave the sheaf, you must sacrifice as a burnt offering to the Lord a lamb a year old without defect, 13together with its grain offering of two-tenths of an ephah of the finest flour mixed with olive oil—a food offering presented to the Lord, a pleasing aroma—and its drink offering of a quarter of a hin of wine. 14You must not eat any bread, or roasted or new grain, until the very day you bring this offering to your God. This is to be a lasting ordinance for the generations to come, wherever you live. 15“ ‘From the day after the Sabbath, the day you brought the sheaf of the wave offering, count off seven full weeks. 16Count off fifty days up to the day after the seventh Sabbath, and then present an offering of new grain to the Lord.
