Le Lévitique 27:15 Références de la Michna : Mishnah Nedarim

וְאִ֨ם־הַמַּקְדִּ֔ישׁ יִגְאַ֖ל אֶת־בֵּית֑וֹ וְ֠יָסַף חֲמִישִׁ֧ית כֶּֽסֶף־עֶרְכְּךָ֛ עָלָ֖יו וְהָ֥יָה לֽוֹ׃

Mais si le consécrateur veut racheter sa maison, il ajoutera un cinquième en sus du prix estimé, et elle sera à lui.

Mishnah Nedarim

[If one says,] “Behold these saplings are a korban if they are not cut down”; or, “This garment is a korban if it is not burnt”, they can be redeemed. [If he says,] “Behold these saplings are a korban until they are cut down”; or, “This garment is a korban until it is burnt”, they cannot be redeemed.
