ציטירנדיקער פּירוש אויף איוב 3:16

But one who fulfills it [a vow] and does not come to regret it and does not seek [rabbinic] release from it, the end proves that he made the vow with a settled mind, and the Torah suspects him that his arrogance brought him to this trait, that he set himself apart. Therefore, he is considered as if he offered a sacrifice on it [a private altar], because the fulfillment is the completion of his intention, just as the sacrifice is the purpose of building a private altar. And this is what is concluded there (Nedarim 22a): Shmuel said: Anyone who makes a vow is called wicked. What is the scriptural source? As it says: If you refrain from making vows, there will be no sin in you (Deuteronomy 23:23). And we learn [through a verbal analogy] from “refrain” to “refrain” — it is written if you refrain [from vowing] and it is written there: There the wicked refrain from angering (Job 3:16).
It seems to me that we can derive from this comparison that just as there [in Job] it deals with refraining from anger, so too here it refers to refraining from anger. For one is only called wicked in this case: when his anger has already subsided, and nevertheless he stands by his vow and does not seek release from it. This reveals retroactively that he did not vow out of anger, since enough time has already passed for anger to subside. And about this it says: There the wicked refrain, meaning he is called wicked when the anger has ceased and he does not seek release from it. If so, he certainly vowed with a settled mind in order to build a private altar for himself. Therefore, one who fulfills it is called wicked, for the way of pride and arrogance is his.
And I will add another verbal analogy, to learn from this [use of the word] refrain to refrain for yourselves from man, whose breath is in his nostrils, for of what account [bameh] is he? (Isaiah 2:22). Just as there [in Isaiah] it refers to a private altar [bamah], so too here it refers to a private altar. And this is what is said here: When a man makes a vow to the Lord — when he is a man in his vow, sound in his mind, and vowed with a settled mind — about him it says, by way of a statement: He shall do according to all that proceeds from his mouth, because he will not come to regret it in the end. But one who vows out of anger, about him it says: He shall not break his word, because he will end up seeking release from it when his anger subsides. And it says a vow to the Lord to exclude vowing out of arrogance, to build a private altar for himself, but rather one who vows for the sake of the Lord.

And now, they did not see the rain At the conclusion of his words, Elihu returns to chide Job’s three companions for not finding an answer. He therefore says, “And now, these three companions of yours, who should have answered you all these things that I said to you... did not see the rain” They are like stillborn babies, who did not see wisdom.
