Leviticus 27:10-16

¹⁰He shall not alter it, nor exchange it, a good for a bad, or a bad for a good. If he shall at all exchange animal for animal, then both it and that for which it is exchanged shall be holy.

¹¹If it is any unclean animal, of which they do not offer as an offering to the LORD, then he shall set the animal before the priest;

¹²and the priest shall evaluate it, whether it is good or bad. As the priest evaluates it, so it shall be.

¹³But if he will indeed redeem it, then he shall add the fifth part of it to its valuation.

¹⁴“‘When a man dedicates his house to be holy to the LORD, then the priest shall evaluate it, whether it is good or bad. As the priest evaluates it, so it shall stand.

¹⁵If he who dedicates it will redeem his house, then he shall add the fifth part of the money of your valuation to it, and it shall be his.

¹⁶“‘If a man dedicates to the LORD part of the field of his possession, then your valuation shall be according to the seed for it. The sowing of a homer of barley shall be valued at fifty shekels of silver.
