Leviticus 23:7-11

Living Bible

⁷ On the first day of this festival, you shall gather the people for worship, and all ordinary work shall cease.^{[a] 8} You shall do the same on the seventh day of the festival. On each of the intervening days you shall make an offering by fire to the Lord.

^9-11 “The Festival of First Fruits: When you arrive in the land I will give you and you reap your first harvest, bring the first sheaf of the harvest to the priest on the day after the Sabbath. He shall wave it before the Lord in a gesture of offering, and it will be accepted by the Lord as your gift.
