Leviticus 27:28-29 - Things Permanently Dedicated To The Lord
28 But nothing which a man has given completely to the Lord, out of all his property, of man or beast, or of the land which is his heritage, may be given away or got back in exchange for money; anything completely given is most holy to the Lord. 29 Any man given completely to the Lord may not be got back: he is certainly to be put to death.
