Leviticus 27:11–13

And if it is any unclean animal that may not be offered as an offering to the Lord, then he shall stand the animal before the priest, and the priest shall value it as either good or bad; as the priest values it, so it shall be. But if he wishes to redeem it, he shall add a fifth to the valuation.

If what they vowed is a ceremonially unclean animal—one that is not acceptable as an offering to the Lord—the animal must be presented to the priest, who will judge its quality as good or bad. Whatever value the priest then sets, that is what it will be. If the owner wishes to redeem the animal, a fifth must be added to its value.

“If the vow involves any of the unclean animals that may not be brought as an offering to the Lord, the animal must be presented before the priest. The priest will set its value, whether high or low; the price will be set as the priest makes the assessment for you. If the one who brought it decides to redeem it, he must add a fifth to the assessed value.

If your vow involves an unclean animal—one that is not acceptable as an offering to the Lord—then you must bring the animal to the priest. He will assess its value, and his assessment will be final, whether high or low. If you want to buy back the animal, you must pay the value set by the priest, plus 20 percent.

But if it is any unclean animal from which they may not present an offering for Yahweh, then he shall present the animal before the priest. And the priest shall set a value on it, either good or bad; as the priest sets your proper value, so it shall be. And if he indeed wants to redeem it, then he shall add a fifth of it onto your proper value.

And if it be any unclean beast, of which they do not offer a sacrifice unto the Lord, then he shall present the beast before the priest: And the priest shall value it, whether it be good or bad: as thou valuest it, who art the priest, so shall it be. But if he will at all redeem it, then he shall add a fifth part thereof unto thy estimation.
