Leviticus 27:13-15

Amplified Bible

¹³ But if he ever wishes to redeem it, then he shall add one-fifth of it to your valuation.

¹⁴ ‘If a man consecrates his house as sacred to the Lord, the priest shall appraise it as either good or bad; as the priest appraises it, so shall it stand. ¹⁵ If the one who consecrates his house should wish to redeem it, then he shall add one-fifth of your valuation price to it, so that it may be his.
