Leviticus 27:9-13 - Redemption Of Vowed Animals

⁹ "'If it is an animal, of which men offer an offering to Yahweh, all that any man gives of such to Yahweh becomes holy. ¹⁰ He shall not alter it, nor change it, a good for a bad, or a bad for a good: and if he shall at all change animal for animal, then both it and that for which it is changed shall be holy.

¹¹ If it is any unclean animal, of which they do not offer as an offering to Yahweh, then he shall set the animal before the priest; ¹² and the priest shall value it, whether it is good or bad. As you the priest values it, so shall it be. ¹³ But if he will indeed redeem it, then he shall add the fifth part of it to its valuation.
