Deuteronomy 12:28 (KJV)

Only thy holy things which thou hast, and thy vows, thou shalt take, and go unto the place which the Lord shall choose:

And thou shalt offer thy burnt offerings, the flesh and the blood, upon the altar of the Lord thy God: and the blood of thy sacrifices shall be poured out upon the altar of the Lord thy God, and thou shalt eat the flesh.

Observe and hear all these words which I command thee, that it may go well with thee, and with thy children after thee for ever, when thou doest that which is good and right in the sight of the Lord thy God.

When the Lord thy God shall cut off the nations from before thee, whither thou goest to possess them, and thou succeedest them, and dwellest in their land;

Take heed to thyself that thou be not snared by following them, after that they be destroyed from before thee; and that thou enquire not after their gods, saying, How did these nations serve their gods? even so will I do likewise.
