Musar zu Jirmejahu 22:16

But even for this sickness - even though it does not have a remedy in the way of other iniquities - there is a remedy if God, may He be blessed, assists one to sanctify His Torah in front of people and to inform people of God’s power and the glory of His majestic Kingship. And his iniquity is removed according to the greatness of the action’s effect, which is the opposite of [the effect of] the action with which he was foolish and with which he sinned. [This is] like the statement of the physicians about the sickness of the body - that it is cured with its opposite, and its resuscitation comes about with its replacement. And King Solomon, peace be upon him, said (Proverbs 16:6), “Iniquity is atoned by kindness and truth.” And we have explained this in the first Gate (1:47) about repentance. And the explanation of the matter of truth that he mentioned is that the sinner should prepare his heart to strengthen the truth, help those seeking faith and remove falsehood and error. For making the truth known and turning it back into a fortress is [an aspect of] the glorification of God - like the matter that is stated (Jeremiah 22:16), “He upheld the rights of the poor and needy; then all was well - was not this to know Me?” And it is stated (Jeremiah 9:5), “through deceit they refuse to know Me.” And our Rabbis, may their memory be blessed, said about the matter of Herod - who killed the sages - asking (Bava Batra 4a) Bava ben Buta advice if he could heal him or cure him of his wound. And he said to him, “You have extinguished the light of the world. Go and involve yourself in the light of the world and make efforts for the building of the Temple.”
