Musar su Deuteronomio 11:17

For if the reward and punishment were the arrangement, then, Heaven Forbid, it will look as if there is a change from desire to desire. Because now he agrees one way and then agrees another way. The matter of Desire is a secret that reveals the emanation that includes all the changes according to awakenings of awakening. This is how it continues from the essence and in nature. The idea is if we sanctify ourselves below, we sanctify Him above in the same nature of the matter that arises. And if he defiles himself, he defiles him from above in the same nature of the matter that has arisen. And if he awakens himself and throws of his ways of exile and binds himself in holiness, he is found in nature sanctified. And the Will of heaven is not changed, for on the contrary, the will is revealed and everything is expected and the authority is given to do so.

And you already know the account of Hillel and Shammai (Shabbath 31a) that the three converts to Judaism said concerning them, "The short-temperedness of Shammai wanted to drive us out from the world, however, the modesty of Hillel brought us under the wing of the Divine Presence" As for Hillel, because of his great modesty, no man could make him angry, for he who holds himself back from anger, will acquire the qualities of modesty and compassion, while from wrath comes the quality of cruelty, as it is written : "And my anger shall blaze forth and I will put you to the sword" (Ex. 22:23). And always in the case of anger we find vengeance, "For the Lord's anger will flare up against you and He will shut up the skies" (Deut. 11:17).
