Bible Verses About Priests: Offering first fruits

Speak unto the children of Israel, and say unto them, When ye be come into the land which I give unto you, and shall reap the harvest thereof, then ye shall bring a sheaf of the firstfruits of your harvest unto the priest:

And he shall wave the sheaf before the LORD, to be accepted for you: on the morrow after the sabbath the priest shall wave it.

And thou shalt go unto the priest that shall be in those days, and say unto him, I profess this day unto the LORD thy God, that I am come unto the country which the LORD sware unto our fathers for to give us.

And the priest shall take the basket out of thine hand, and set it down before the altar of the LORD thy God.
