During the time you celebrate the Festival of Weeks, hold a holy meeting on the day of firstfruits when you present an offering of new grain to the Lord. Don't do any of your normal work.
On both the first day and on the seventh day you are to have a holy meeting. You must not work on those days, except to prepare food. That is all you are allowed to do.
You are also to observe the Festival of Harvest when you present the firstfruits of the produce from what you've sown in the fields. Lastly you are to observe the Festival of Gathering-In the Harvest at the end of the year, when you gather in the harvest of the rest of your crops from the field.
“Tell the Israelites that when you enter the land that I'm giving you and you harvest your crops, take a stack of grain from the firstfruits of your harvest to the priest.
For seven days you shall present food offerings to the Lord. There is to be a holy meeting on the seventh day. You must not do any of your usual work.”
