Leviticus 27:28

²⁸All thing that is hallowed to the Lord, whether it is man, or beast, (or) whether (the) field of his heritage, it shall not be sold, neither it shall be able to be again-bought; whatever thing is hallowed once, it shall be holy of holy things to the Lord, (Everything that is dedicated to the Lord, whether it is a man, or a beast, or the field of his inheritance, shall not be sold, nor shall it be able to be bought back; once something is dedicated, it shall be a most holy thing to the Lord,)
