Leviticus 27:8-18

8 `And if he is poorer than thy valuation, then he hath presented himself before the priest, and the priest hath valued him; according to that which the hand of him who is vowing doth reach doth the priest value him.
9 `And if [it is] a beast of which they bring near an offering to Jehovah, all that [one] giveth of it to Jehovah is holy;
10 he doth not change it nor exchange it, a good for a bad, or a bad for a good; and if he really change beast for beast, -- then it hath been -- it and its exchange is holy.
11 `And if [it is] any unclean beast of which they do not bring near an offering to Jehovah, then he hath presented the beast before the priest,
12 and the priest hath valued it; whether good or bad, according to thy valuation, O priest, so it is;
13 and if he really redeem it, then he hath added its fifth to thy valuation.
14 `And when a man sanctifieth his house, a holy thing to Jehovah, then hath the priest valued it, whether good or bad; as the priest doth value it so it standeth;
15 and if he who is sanctifying doth redeem his house, then he hath added a fifth of the money of thy valuation to it, and it hath become his.
16 `And if of the field of his possession a man sanctify to Jehovah, then hath thy valuation been according to its seed; a homer of barley-seed at fifty shekels of silver;
17 if from the year of the jubilee he sanctify his field, according to thy valuation it standeth;
18 and if after the jubilee he sanctify his field, then hath the priest reckoned to him the money according to the years which are left, unto the year of the jubilee, and it hath been abated from thy valuation.
