Leviticus 23:4-14

“ ‘These are the LORD’s appointed festivals, the sacred assemblies you are to proclaim at their appointed times: The LORD’s Passover begins at twilight on the fourteenth day of the first month. On the fifteenth day of that month the LORD’s Festival of Unleavened Bread begins; for seven days you must eat bread made without yeast. On the first day hold a sacred assembly and do no regular work. For seven days present a food offering to the LORD. And on the seventh day hold a sacred assembly and do no regular work.’ ” The LORD said to Moses, “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. He 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. On the day you wave the sheaf, you must sacrifice as a burnt offering to the LORD a lamb a year old without defect, together 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. You 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.
