Le Deutéronome 12:25 Midrash : Mekhilta DeRabbi Yishmael

לֹ֖א תֹּאכְלֶ֑נּוּ לְמַ֨עַן יִיטַ֤ב לְךָ֙ וּלְבָנֶ֣יךָ אַחֲרֶ֔יךָ כִּֽי־תַעֲשֶׂ֥ה הַיָּשָׁ֖ר בְּעֵינֵ֥י יְהוָֽה׃

Ne le mange point! Afin que tu sois heureux, toi et tes enfants après toi, pour avoir fait ce qui plaît au Seigneur.

Mekhilta DeRabbi Yishmael
