Deuteronomy 26:1-4

And it shall be, when thou art come in unto the land which Jehovah thy God giveth thee for an inheritance, and possessest it, and dwellest therein, that 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. And 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. And the priest shall take the basket out of thy hand, and set it down before the altar of Jehovah thy God.
