Apabila seorang laki-laki bernazar kepada Yang Mahakekal atau bersumpah untuk mengikat dirinya dengan suatu larangan, janganlah ia melanggar perkataannya; ia harus melakukan segala sesuatu sesuai dengan apa yang keluar dari mulutnya.

How much more so will he who fears the Lord (Exod. 9:20) give more love, awe, fear, and humility, will he worry because of his sins, and will he be concerned lest he increase his sins with the iniquity of erring in the statements [concerning] the knowledge of the holy God (Josh. 24:19) lest his soul offer itself in restitution (Isa. 53:10). His only recourse (Esther 4:11) and the territory of his inheritance (Deut. 32:9) is to strip himself, and to cut and offer [himself] as a complete sin offering. He will be morally strong to bind with a bond forbidding (Num. 30:3) that which he has not heard from his teachers. He makes even all his paths (Prov. 5:21) and the utterances of his lips (Ps. 21:3). For if he falls (Deut. 22:8), who will raise him up? (Gen. 49:9). The Lord alone will lead him, and there is no strange god with him (Deut. 31:12) who has apportioned to test in them and afflicted [them] because of their iniquities (Ps. 107.17).

The reason is because the Torah says “He shall do according to all that proceeds out of his mouth” (Numbers 30:3), since the speech that is spiritual is similar to the sperm that is physical. Just like from the lower Brit one must not emit semen in vain, but only into a female, so too one must not say words in vain except for the sake of bringing oneself to a place of action, which is the female, and thus he unites the Brit of the tongue with the female. If he does not fulfill it, Chas Veshalom, then it is like he emitted semen in vain, which is the voice and speech that comes out of the Brit of the tongue, and therefore he will also damage the Brit with semen in vain, since a transgression leads to a transgression.

Now, because the prophets knew this great secret, they could nullify all the decrees of the Upper Court of Judgement (Beit Din Shel Ma’alah). This is the secret of the verse,198Samuel II 23:3 “The righteous-Tzaddik rules over the fear of God-Elohi”m-אלהי״ם.” The Holy One, blessed is He, said, “I rule over man and who rules over me? The righteous-Tzaddik. For, I issue a decree and he annuls it.”199Talmud Bavli, Mo’ed Katan 16b This is the secret of the verse,200Exodus 32:11 “Moshe implored-Vayichal-ויחל before HaShem-יהו״ה his God.” That is, he elevated his thought to the place where the decree is annulled. Thus, about this, our sages, of blessed memory, stated,201Midrash Shemot Rabba 43:4 “He begged Him until He nullified His vow.” This is because understanding-Binah is the place of the vow-Neder-נדר, since the place of understanding-Binah is the matter of the beginning of the seven Sefirot, and this is the secret of annulment-Vayichal-ויחל.202As in the verse (Numbers 30:3), “If a man makes a vow-Neder-נדר… he shall not break-Yacheil-יחל his word.” This is the meaning of what our sages, of blessed memory, stated,203Talmud Bavli, Yevamot 105a “From where do we know that even once the sentence is sealed, it may be torn up? From the verse,204Deuteronomy 4:8 ‘Who-Mee-מי is like HaShem-יהו״ה our God, whenever we call upon Him.’”
