Leviticus 27:13-15

Young's Literal Translation

¹³ and if he really redeem it, then he hath added its fifth to thy valuation.

¹⁴ `And when a man sanctifieth his house, a holy thing to Jehovah, then hath the priest valued it, whether good or bad; as the priest doth value it so it standeth;

¹⁵ and if he who is sanctifying doth redeem his house, then he hath added a fifth of the money of thy valuation to it, and it hath become his.
