Il y a quatre middoth dans le deoth (tempéraments): facilement en colère et facilement apaisés —son gain est annulé par sa perte; irrité avec difficulté et pacifié avec difficulté—sa perte est annulée par son gain. [Si quelqu'un est rapidement irrité par toutes choses, même s'il est facilement apaisé, sa perte est plus que son gain. Car la plupart de ses actes sont défectueux dans la mesure où il se met facilement en colère contre tout. Mais si l'on se met en colère avec difficulté, même s'il a le mal middah d'être pacifié avec difficulté, sa (relativement) petite perte, étant pacifiée avec difficulté, est annulée par son gain (relativement) plus grand, étant irrité avec difficulté, de sorte que la plupart de ses actes sont louables. Certaines versions sont à l'opposé de cela; mais cela semble être la bonne version.]; irrité avec difficulté et facilement apaisé—un chasid; facilement en colère et pacifié avec difficulté— un méchant.

This is the textual variant that we [follow]: [a person who is] easy to anger and easy to appease -- his gain is canceled by his loss. [A person who is] hard to anger but [also] hard to appease -- his loss is canceled by his gain: A man who get angry quickly about everything - even though he goes back and is quickly appeased - his loss is greater than his reward; as most of his deeds are spoiled, since he is easy to anger about each and every thing. But [if he is] hard to anger - even though he has a bad trait [in] that he is hard to appease - his great reward [in] that he is hard to anger cancels out his small loss [in] that he is hard to appease, and most of his deeds are refined. And some [follow] the variant [that has] the opposite, and [the first] variant seems more like the main [one].
Observe how he called the patient one, whose patience is excessive to the point that he approaches lack of feeling concerning the matter of anger, a pious man. And he called someone with the vices of the trait of anger, evil.
HARD TO ANGER AND EASY TO APPEASE—THIS IS A PIOUS PERSON. But there is nobody with such a temperament that he never angers. For who was greater in humility than Moses, of whom the verse says “Moses became angry with the commanders of the army” (Numbers 31:14)—Midrash Shmuel. Greater than this is the verse “listen here, you rebels!” (Numbers 20:10), but it does not say explicitly that he was angry.
