Vayikra 27:11-13

Orthodox Jewish Bible

¹¹ And if it be any behemah temeiah, of which they do not offer a korban unto Hashem, then he shall present the behemah before the kohen;

¹² And the kohen shall value it, whether it be tov or rah; as thou valuest it, who art the kohen, so shall it be.

¹³ But if he will at all redeem it, then he shall add chamishto (a fifth part thereof) unto thy evaluation.
