“Speak to the Israelites and tell them,‘When you enter the land that I am about to give to you and you gather in its harvest, then you must bring the sheaf of the first portion of your harvest to the priest,
Firstfruits“‘Also, on the day of the first fruits, when you bring a new grain offering to the LORD during your Feast of Weeks, you are to have a holy assembly. You must do no ordinary work.
Then you are to celebrate the Feast of Weeks before the LORD your God with the voluntary offering that you will bring, in proportion to how he has blessed you.
