Leviticus 27:11, 27
But 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. / But if it is among the unclean animals, then he may redeem it according to your valuation and add a fifth of its value. If it is not redeemed, then it shall be sold according to your valuation.
