Leviticus 23:3-11

³“‘Six days shall work be done, but on the seventh day is a Sabbath of solemn rest, a holy convocation; you shall do no kind of work. It is a Sabbath to the LORD in all your dwellings.

⁴“‘These are the set feasts of the LORD, even holy convocations, which you shall proclaim in their appointed season.

⁵In the first month, on the fourteenth day of the month in the evening, is the LORD’s Passover.

⁶On the fifteenth day of the same month is the feast of unleavened bread to the LORD. Seven days you shall eat unleavened bread.

⁷In the first day you shall have a holy convocation. You shall do no regular work.

⁸But you shall offer an offering made by fire to the LORD seven days. In the seventh day is a holy convocation. You shall do no regular work.’”

⁹The LORD spoke to Moses, saying,

¹⁰“Speak to the children of Israel, and tell them, ‘When you have come into the land which I give to you, and shall reap its harvest, then you shall bring the sheaf of the first fruits of your harvest to the priest.

¹¹He shall wave the sheaf before the LORD, to be accepted for you. On the next day after the Sabbath the priest shall wave it.
