Leviticus 23:4-11
The Festival of Passover and Unleavened Bread
23:4 “‘These are the Lord’s appointed times, holy assemblies, which you must proclaim at their appointed time.
23:5 In the first month, on the fourteenth day of the month, at twilight, is a Passover offering to the Lord.
23:6 Then on the fifteenth day of the same month will be the festival of unleavened bread to the Lord; seven days you must eat unleavened bread.
23:7 On the first day there will be a holy assembly for you; you must not do any regular work.
23:8 You must present a gift to the Lord for seven days, and the seventh day is a holy assembly; you must not do any regular work.’”
The Presentation of First Fruits
23:9 The Lord spoke to Moses:
23:10 “Speak to the Israelites and tell them, ‘When you enter the land that I am about to give to you and you gather in its harvest, then you must bring the sheaf of the first portion of your harvest to the priest,
23:11 and he must wave the sheaf before the Lord to be accepted for your benefit – on the day after the Sabbath the priest is to wave it.
