“You must celebrate the Feast of Weeks. Offer to God the first things you harvest from the crops you planted in your fields. “You must celebrate the Feast of Shelters in the fall, when you gather all the crops from your fields.
“Tell the people of Israel: ‘You will enter the land I will give you and gather its harvest. At that time you must bring the first bundle of grain from your harvest to the priest.
For seven days you will bring an offering made by fire to the Lord. There will be a holy meeting on the seventh day, and on that day you must not do any regular work.’ ”
