אבות ד׳:י״ח - ד׳:י״ט

"Do not try to assuage the anger of your friend at the time of his anger": As it is written (Exodus 33:14), "My presence (literally, face) will go and I will give you to rest" - said the Holy One, blessed be He, to Moshe, "Wait until My face of anger passes" (Berakhot 7a).

"do not console him at the time when his deceased lies before him": As at the time of the [Temple's] destruction - as if it were possible - the Holy One, blessed be He, was mourning. [When] the ministering angels tried to console Him, the holy spirit answered them, "Do not rush to console Me."

"do not question him at the time of his vow": to find an opening (loophole) to annul his vow. Because then, on each and every opening that you find for him, he will say, "I made the vow with that in mind [meaning that he wanted the vow to be operative in spite of the loophole]" - and then you will no longer be able to find him an opening. And we have found that when the Holy One, blessed be He, swore to Moshe that he should not enter the Land, he did not plead immediately, but rather waited and afterwards began to plead.

"at the time of his humiliation": when he is humiliated by sin, as he is embarrassed from everyone. And so [too] do you find that when Adam sinned, the Holy One, blessed be He, did not reveal Himself to them until they made loincloths, as it is written (Genesis 3:7), "and they made for themselves loincloths," and afterwards, "and they heard the voice of the Lord God."

"'When your enemy falls, do not be happy'": It is a verse in Proverbs, but Shmuel the Younger was accustomed to rebuking people with this attribute.

"'Lest God see and it be bad in His eyes'": that you have made Him in your heart as if He is your agent to fulfill your desire.

"'and He turn from him [the enemy] His anger'": Since it did not write, "and He return (veshav) but rather, and He turn (veheshiv), it is implied that He removes it from your enemy and turns it upon you.
