Leviticus 27:31-33

Darby Translation

³¹ And if any one will at all redeem of his tithes, he shall add thereto the fifth thereof.

³² And as to every tithe of the herd, or of the flock, of whatever passeth under the rod, the tenth shall be holy to Jehovah.

³³ He shall not search whether it be good or bad, neither shall he change it; and if he change it at all, then both it and the exchange thereof shall be holy; it shall not be redeemed.
