Leviticus 27:30-33

27:30 And all the tithe of the land, [whether] of the seed of the land, [or] of the fruit of the tree, [is] the LORD’S: [it is] holy unto the LORD. 27:31 And if a man will at all redeem [ought] of his tithes, he shall add thereto the fifth [part] thereof. 27:32 And concerning the tithe of the herd, or of the flock, [even] of whatsoever passeth under the rod, the tenth shall be holy unto the LORD. 27:33 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 change thereof shall be holy; it shall not be redeemed.
