Leviticus 27:30-34

Leeser(i) 30 And every tithe of the land, of the seed of the land, or of the fruit of the tree, belongeth to the Lord; it is holy unto the Lord. 31 And if a man will redeem any part of his tithe, its fifth part shall he add thereto. 32 And concerning the tithe of the herds, or of the flocks, 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 should change it, then both it and the exchange thereof shall be holy; it shall not be redeemed. 34 These are the commandments, which the Lord commanded Moses for the children on mount Sinai.
