Leviticus 27:10-18

¹⁰The person must not alter or change such an animal, a good one for a bad one or a bad for a good. If he does at all change one animal for another, then both it and the one for which it is exchanged become holy.

¹¹However, if what the person has vowed to give Yahweh is in fact unclean, so that Yahweh will not accept it, then the person must bring the animal to a priest.

¹²The priest will value it, by the market value of the animal. Whatever value the priest places on the animal, that will be its value.

¹³If the owner wishes to redeem it, then a fifth of its value is to be added to its redemption price.

¹⁴When a man sets apart his house as a holy gift to Yahweh, then the priest will set its value as either good or bad. Whatever the priest values it, so it will be.

¹⁵But if the owner who set apart his home wishes to redeem it, he must add a fifth of its value to its redemption price, and it will belong to him.

¹⁶If a man sets apart some of his own land, then the valuation of it will be in proportion to the amount of seed required to plant it—a homer of barley will be valued at fifty shekels of silver.

¹⁷If he sets apart his field during the year of Jubilee, the valuation of it will stand.

¹⁸But if he sets apart his field after the year of Jubilee, then the priest must calculate the value of the field by the number of years that remain until the next year of Jubilee, and the valuation of it must be reduced.
