‘Also on the day of the firstfruits, when you bring a new grain offering to the Lord at your Feast of Weeks, you shall have a holy convocation. You shall do no customary work.
and the Feast of Harvest, the firstfruits of your labors which you have sown in the field; and the Feast of Ingathering at the end of the year, when you have gathered in the fruit of your labors from the field.
“Speak to the children of Israel, and say to them: ‘When you come into the land which I give to you, and reap its harvest, then you shall bring a sheaf of the firstfruits of your harvest to the priest.
‘And in the seventh month, on the first day of the month, you shall have a holy convocation. You shall do no customary work. For you it is a day of blowing the trumpets.
On the first day there shall be a holy convocation, and on the seventh day there shall be a holy convocation for you. No manner of work shall be done on them; but that which everyone must eat—that only may be prepared by you.
But you shall offer an offering made by fire to the Lord for seven days. The seventh day shall be a holy convocation; you shall do no customary work on it.’ ”
