Musar do Rodzaju 4:26

And know that when the listener concedes to the evil speech, his lot and measured portion (a scriptural expression [in Jeremiah 13:25], “This shall be your lot, your measured portion”) is with the one who speaks evil speech. For they will surely say, “See, the listeners accepted the thing, and that is a sign that the thing is really true. Even if the listener tilted [his] ear and made himself appear to be listening and believing these words in front of people, this also helps the evil, causes a disgrace to [the subject of the talk], and strengthens the hands of the one who brings his evil speech against people. And King Solomon, peace be upon him, said (Proverbs 25:23), “A north wind tehollel rain, and a raging face, a hidden tongue.” Its explanation is, just like a north wind scatters the clouds and prevents the rain, so does a raging face stop evil speech. For when the speaker sees the face of the listener enraged, he will stop the voice of his raining words. But if he sees that the listener is listening to him, he will not stop his mouth from his lies; and tomorrow will be like today. For he will repeat his stupidity, to always speak false speech; and his tongue will follow the rain of his falsehoods. Tehollel is from the expression challilah (forbid or prevent). And likewise (Numbers 30:3), “he shall not annul (yechal) his word”; and also (Genesis 4:26), “it was then huchal to call,” [which means] it was then prevented.

Chazal have said (Reishith Chochmah, Sha'ar Ha'anavah 4): "In three instances the Holy One Blessed be He overlooked idol worship; but He did not overlook machloketh. First, in the generation of Enosh, when men began to serve idols, as it is written: 'Then they began to call [idols] in the name of the L-rd.' But, because there was peace among them, the Holy One Blessed be He allowed them a hiatus. In the generation of the flood, however, because there was machloketh among them, so that they stole and plundered from each other, the Holy One Blessed be He did not relent, as it is written (Ibid. 6:"13): 'Because the earth was filled with violence by them, etc.' Second, in the generation of the desert when the Jews came to make the golden calf, the Holy One Blessed be He forgave them; but when they lapsed into machloketh, the Holy One Blessed be He did not overlook it. For wherever you find 'and they protested' [vayalinu] of machloketh, you find a great smiting, the most extreme instance being the Korach rebellion. Third, the image of Micah. Because there was peace among them, they were given a grace period, as it is written (Judges 18:30): 'And the children of Dan set up the image; and Yehonathan, the son of Menasheh, he and his sons were priests to the tribe of Dan until the day of the captivity of the land.' But when the tribes contended with the tribes of Judah and Benjamin, and there was no peace among them, they became scourges to each other. When the one sinned, the Holy One Blessed be He would bring the other upon him and exact payment from him, as it is written (II Chronicles 13:17): 'And Aviyya and his people slew them with a great slaughter, so there fell slain of Israel five hundred thousand chosen men.' And when the tribes of Judah and Benjamin sinned, the ten tribes came and exacted punishment of them, as it is written (Ibid. 28:6): 'For Pekach, the son of Remalyahu, slew in Judah a hundred and twenty thousand in one day.'" We are hereby taught that men of machloketh become instruments of destruction, one to the other.

We must appreciate that when G–d created different worlds, He named, i.e. formed and defined them by means of a combination of the letters of the alphabet. Our sages say that Betzalel understood the mystery of the combinations of all of these letters which make up the names [definitions] of all things found in this world (Berachot 55 based on the word שם in Exodus 35,30). Early man, who was still בצלם אלוקים, was still able to understand the significance of the names of G–d, and used these names to serve Him in holiness and love in order to cleave to Him. This condition came to an end with the generation of Enosh, as we have explained earlier based on Bereshit Rabbah. When we read in Genesis 4,26 that during the lifetime of Enosh אז הוחל לקרא בשם ה', "then one began to profane the name of the Lord," the meaning is that people no longer used His Name in holiness but desecrated it. The expression הוחל indicates something that is profane, חולין. This situation continued until the advent of the deluge. When the Torah speaks about המה הגבורים אשר היו מעולם אנשי השם, "they were the heroes of old, men of the "Name" (Genesis 6,4), this means that these people used the name of G–d to manipulate the universe, as described in the Zohar, Sullam edition page 209. The expression אנשי השם in Genesis, and the expression ויקוב את השם in Leviticus 24,11, where the Torah refers to the blasphemer, suggests a similar misuse of the Holy Name of G–d in both instances. It was the ability of these people to use G–d's name in order to manipulate it that made them disregard the warnings of an impending deluge. All this is described at greater length in the Zohar. We find that the people of Jerusalem are described by the prophet Ezekiel 12,19 as also having displayed misplaced optimism concerning the prophecies of doom by Jeremiah. The people's very knowledge of G–d's name was what misled them. This is the justification for the reference in Ezekiel to these people as "dwellers in ruins" when in fact they were still dwelling in Jerusalem.
