Leviticus 27:11-13

Complete Jewish Bible

¹¹ If the animal is an unclean one, such as may not be used in an offering to Adonai, he must set it before the cohen; ¹² and the cohen is to set a value on it in relation to its good and bad points; the value set by you the cohen will stand. ¹³ But if the person making the vow wishes to redeem the animal, he must add one-fifth to your valuation.
