וְאִם־גָּאֹ֤ל יִגְאַל֙ אֶת־הַשָּׂדֶ֔ה הַמַּקְדִּ֖ישׁ אֹת֑וֹ וְ֠יָסַף חֲמִשִׁ֧ית כֶּֽסֶף־עֶרְכְּךָ֛ עָלָ֖יו וְקָ֥ם לֽוֹ׃
밭을 구별하여 드린 자가 그것을 무르려면 정가한 돈에 그 오분 일을 더할지니 그리하면 그것이 자기 소유가 될 것이요
Rashi
ואם גאל יגאל AND IF HE WILL IN ANY WAY REDEEM IT “he” means, the man who dedicated it; then he shall add a fifth part to this fixed price (not a fifth of the fifty shekels, but a fifth of the value determined by this calculation is to be added to that value).
Ibn Ezra
The vav in if he redeems here functions like the Arabic f . The verse is a continuation of the previous verses, since Scripture is primarily discussing valuation — in the case when the field is redeemed, and in the case when the field is not redeemed.
