Musar su Esodo 12:28

The third path is [that] when he hears reproof from the sages that are reprimanding [him], he listens, submits, repents and accepts in his heart all the words of reprimand - and not subtract one thing from their words. And behold that man went out from darkness to a great light at that instant. For at the time that he listened and paid attention and his heart understood and repented and accepted the words of the rebuker on the day he heard them, and took upon himself to do like everything that the holders of Torah instructed him - from that day onward - to be careful as the knowers of understanding of the times instructed him: His repentance is effective and he is changed into a different person. And from the time that he accepted this in his heart, he acquired merit and reward for his soul for all of the commandments and ethical acts. And happy is he for justifying his soul in a short time. And so did our Rabbis, may their memory be well, say (Mekhilta d'Rabbi Yishmael, 12:28), "And the Children of Israel went and did' - and did they do it right away? Did they not only do it on the fourteenth of the month? Rather since they accepted upon themselves to do it, [the verse] counts it for them as if they did it immediately." And he said in Avot of Rabbi Natan (Avot d'Rabbi Natan 22), "Anyone whose actions are greater than his wisdom - his wisdom will endure, as it is stated (Exodus 24:7), 'we shall do and we shall listen.'" The explanation of the thing is that when a man accepts upon himself with a faithful heart to keep and do according to the Torah that he was taught and about the law which those sitting upon judgement told him - from that day, he has the reward for all of the commandments that his ear heard and that he understood, [as well as] for all of the things which his ear has still not heard about. So he wore righteousness and acquired merit for all of what was revealed to him and for all that was hidden from his eyes. And after this, he should study from and regularly attend the doors of those that reprimanded him, and comprehend [the teachings] of all that teach him. And it comes out that the actions of this man are greater than his wisdom, since he did not know the thing, but behold its reward (for it) is with him. And it is like the matter that Israel said, "We shall do and we shall listen," at [Mount] Sinai - as they had the acceptance of the deed upon themselves, precede the listening. And in no other way it is possible for the actions of a man to be greater than what he knows.

The third thing that can stir the heart to repentance is when he hears the chastisement of the wise and of those who reprove him, and this arouses his heart to repent, and he receives upon himself all the words of these rebukes. From the time that he accepts them, this man earns great merit, and in a short space of time he has gone forth from darkness to light, and he has gained reward and merit for all of the commandments and all of the chastisements, inasmuch as he has resolved to receive them upon himself. And happy is he who receives this upon himself, for he has won merit in a brief moment. And thus did our Sages, of blessed memory, say "And the children of Israel went and did." Now had they already done this (i.e., prepared the Passover)? Surely, they did not do so until the fourteenth day of the month! But when they took it upon themselves to do it, Scripture ascribes it to them as though they had already done it" (Mechilta on Exodus 12:28). And thus did our Sages say, "All whose deeds are greater than his wisdom, his wisdom will endure" (Aboth 3:12). As it is said, "We will do and we will hear!" (Ex. 24:7).
