אִישׁ֩ כִּֽי־יִדֹּ֨ר נֶ֜דֶר לַֽיהוָ֗ה אֽוֹ־הִשָּׁ֤בַע שְׁבֻעָה֙ לֶאְסֹ֤ר אִסָּר֙ עַל־נַפְשׁ֔וֹ לֹ֥א יַחֵ֖ל דְּבָר֑וֹ כְּכָל־הַיֹּצֵ֥א מִפִּ֖יו יַעֲשֶֽׂה׃
Si un homme fait un vœu au Seigneur, ou s’impose, par un serment, quelque interdiction à lui-même, il ne peut violer sa parole: tout ce qu’a proféré sa bouche, il doit l’accomplir.
Targum Jonathan on Numbers
A man, a son of thirteen when he shall have vowed a vow before the Lord, or have sworn an oath, saying, I will withhold from such a thing which is permitted to me, shall not be allowed to relax his word (at his own will): nevertheless, the house of judgment (beth dina) can absolve him; but if they absolve him not, whatsoever hath gone out of his mouth he shall perform.
