Leviticus 27:30-33 King James Version (KJV)
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.
31 And if a man will at all redeem ought of his tithes, he shall add thereto the fifth part thereof.
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.
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.
Leviticus 27:30-33 New International Version (NIV)
30 “‘A tithe of everything from the land, whether grain from the soil or fruit from the trees, belongs to the Lord; it is holy to the Lord. 31 Whoever would redeem any of their tithe must add a fifth of the value to it. 32 Every tithe of the herd and flock—every tenth animal that passes under the shepherd’s rod—will be holy to the Lord. 33 No one may pick out the good from the bad or make any substitution. If anyone does make a substitution, both the animal and its substitute become holy and cannot be redeemed.’”
