Leviticus 27:30-33

30And as to every titheH4643 of the landH776, of the seedH2233 of the landH776, and of the fruitH6529 of the treeH6086, it is Jehovah's: it is holyH6944 to Jehovah.

31And if any oneH376 will at all redeemH1350 of his tithesH4643, he shall addH3254 thereto the fifthH2549 thereof.

32And as to every titheH4643 of the herdH1241, or of the flockH6629, of whatever passeth under the rodH7626, the tenthH6224 shall beH1961 holyH6944 to Jehovah.

33He shall not search whether it beH1961 goodH2896 or badH7451, neither shall he change it; and if he change it at all, then both it and the exchangeH4171 thereof shall beH1961 holyH6944; it shall not beH1961 redeemedH1350.
