Leviticus 27:30-33

  30 H4643 "‘All the tithe H776 of the land, H2233 whether of the seed H776 of the land H6529 or of the fruit H6086 of the trees, H3068 is Yahweh's. H6944 It is holy H3068 to Yahweh.
  31 H376 If a man H1350 redeems H1350 anything H4643 of his tithe, H3254 he shall add H2549 a fifth part to it.
  32 H4643 All the tithe H1241 of the herds H6629 or the flocks, H5674 whatever passes H7626 under the rod, H6224 the tenth H6944 shall be holy H3068 to Yahweh.
  33 H1239 He shall not search H2896 whether it is good H7451 or bad, H4171 neither shall he change H4171 it: and if he changes H4171 it at all, H8545 then both it and that for which it is changed H6944 shall be holy. H1350 It shall not be redeemed.'"
