Leviticus 27:20-30

20 And if he do not redeem the field, but should sell the field to another man, he shall not after redeem it.
21 But the field shall be holy to the Lord after the release, as separated land; the priest shall have possession of it.
22 And if he should consecrate to the Lord of a field which he has bought, which is not of the field of his possession,
23 the priest shall reckon to him the full valuation from the year of release, and he shall pay the valuation in that day holy to the Lord.
24 And in the year of release the land shall be restored to the man of whom the other bought it, whose the possession of the land was.
25 And every valuation shall be by holy weights: the didrachm shall be twenty oboli.
26 And every first-born which shall be produced among thy cattle shall be the Lord's, and no man shall sanctify it: whether calf or sheep, it is the Lord's.
27 But if he should redeem an unclean beast, according to its valuation, then he shall add the fifth part to it, and it shall be his; and if he redeem it not, it shall be sold according to its valuation.
28 And every dedicated thing which a man shall dedicate to the Lord of all that he has, whether man or beast, or of the field of his possession, he shall not sell it, nor redeem it: every devoted thing shall be most holy to the Lord.
29 And whatever shall be dedicated of men, shall not be ransomed, but shall be surely put to death.
30 Every tithe of the land, both of the seed of the land, and of the fruit of trees, is the Lord's, holy to the Lord.
