About Feast of First Fruits
The LORD instructs Israel after they enter the land that Adonai gives them; they are to give of the First Fruit of the harvest, a sheaf to the High Priest. On the day after Shabbat, the High Priest is to wave the sheaf offering before Adonai so that they would be accepted.
There is a male lamb without defect in its first year, to be offered as a burnt offering (Yeshua). There is a meal to be prepared but not eaten until the day they bring the wave offering before Adonai. This is a permanent regulation through all generations, no matter where you live.
