Leviticus 23:9

⁷And the first day shall be a holy convocation to you: ye shall do no servile work.

⁸And ye shall offer whole burnt offerings to the Lord seven days; and the seventh day shall be a holy convocation to you: ye shall do no servile work.

— Leviticus 23:9 —

¹⁰Speak to the children of Israel, and thou shalt say to them, When ye shall enter into the land which I give you, and reap the harvest of it, then shall ye bring a sheaf, the firstfruits of your harvest, to the priest;

¹¹and he shall lift up the sheaf before the Lord, to be accepted for you. On the morrow of the first day the priest shall lift it up.
