Deuteronomy 26:2-4

2that thou shalt take of the first of all the fruit of the ground, which thou shalt bring in from thy land that Jehovah thy God giveth thee; and thou shalt put it in a basket, and shalt go unto the place which Jehovah thy God shall choose, to cause his name to dwell there.

3And thou shalt come unto the priest that shall be in those days, and say unto him, I profess this day unto Jehovah thy God, that I am come unto the land which Jehovah sware unto our fathers to give us.

4And the priest shall take the basket out of thy hand, and set it down before the altar of Jehovah thy God.
