Бамидбар 30:12 Мидраш: Mekhilta DeRabbi Yishmael & Sifrei Bamidbar

וְשָׁמַ֤ע אִישָׁהּ֙ וְהֶחֱרִ֣שׁ לָ֔הּ לֹ֥א הֵנִ֖יא אֹתָ֑הּ וְקָ֙מוּ֙ כָּל־נְדָרֶ֔יהָ וְכָל־אִסָּ֛ר אֲשֶׁר־אָסְרָ֥ה עַל־נַפְשָׁ֖הּ יָקֽוּם׃

и муж ее услышал, и молчал, и не запретил ей; тогда все ее обеты будут стоять, и всякая связь, которой она связывала свою душу, будет стоять.

Mekhilta DeRabbi Yishmael

R. Yishmael says: Come and see the mercies of the One who spoke and brought the world into being, for flesh and blood. For a man acquires himself with money from the hands of Heaven, as it is written (Numbers 30:12) "When you take the sum of the children of Israel according to their number, then each man shall give the ransom of his soul to the L–rd, etc.", and (II Kings 12:5) "each man, the money for the valuation of his soul," and (Mishlei 13:8) "A man's wealth may redeem his soul," and (Daniel 4:24) "But, O king, let my counsel be acceptable to you. Redeem your soul through charity," and (Job 33:23-24) "If there will be for him but a single defending angel from a thousand to declare a man's uprightness for him, then He will be gracious to him and He will say: Redeem him from descending to the grave I have found kofer for Him!"

Sifrei Bamidbar

(Bamidbar 30:12) "and her husband heard": to exclude one who was deaf. "And her husband heard": This tells me only of one who himself heard (the vow). Whence do I derive (the same for) his being informed by others? From (13) "on the day of his hearing," "and he was silent to her": to (the end of) confirmation. You say this, but perhaps (the "silence" intended is the silence of) taunting. (This cannot be, for (Ibid. 15) "And if her husband be silent to her from day to day" already speaks of (the silence of) taunting. How, then, am I to understand "and he was silent to her"? As referring to (the silence of) confirmation. (Ibid. 12) "then all of her vows shall stand": If she vowed and he confirmed (her vow by his silence), and he later annulled it, I might think that it is annulled. And how would I understand "then all of her vows shall stand"? If he did not annul them. Or, even if he did annul them, and how would I understand "and he annul her vow"? If he had not confirmed it. Or, even if he did confirm it? It is, therefore, written (Ibid. 12) "shall stand."
