And do not be easy to anger: Do not prepare yourself to anger and irritability. And they have already gone far in disgracing anger and irritability. And the strongest of their words is their saying (Shabbat 105b), "Anyone who gets angry is as if he worships idols." And they made it adjacent to his saying (Psalms 81:10), "You shall have no foreign god, you shall not bow to an alien god" - meaning to say that the two things are one.
and repent one day before your death: And [since] he does not know when he will die - maybe today or maybe tomorrow - all of his days will be in repentance. But his saying, "And warm yourself by the fire of the sages," is not from their words with which he educated them, but rather is what he heard from someone else but he would [nonetheless] recount it. And because of this it was not counted among his [three] things. And the intention of this command that he is telling you is that when you associate with the sages and with men of virtues, do not be playful with them and do not be arrogant towards them, but let your association be to let them know that you will approach them at the time that they will bring you close. And do not add to come closer to them than that which they have brought you close - that you not lose their intention about you, and you reverse their love to hate and the benefit that you hoped to get from them not reach you. And he compared this to one who warms himself by the fire - as if he sits far from it, he will enjoy its heat and get benefit from its light. But if he is negligent with himself and continues to get closer to it, he will get burnt and the benefit will turn into damage. And this is the content of his saying metaphorically, "And warm yourself by the fire of the sages, but be cautious around their coals that you should not be burned." And afterwards he added to frighten about this and he said, "Do not think that if they bite you with their tongues that you will come back and appease them with your words and they will be appeased." As truly they will not listen to the voice of a charmer like the Seraph does not listen to it, as it stated (Psalms 55:6), "Which does not hear the voice of charmers." And you should know this from the matter of Gechazi in that which he was audacious in front of his teacher, Elisha, and who fell into a disgusting disease, as is elucidated from the words of the sages about the matter of the four men who were "leprous" (metsuarim). And so [too] with Rabbi Yehoshua ben Perachiah and with all of them is the damage that came to them elucidated - and with others that 'burnt their stew.'
