Musar su Salmi 79:12

And, in the same way, they will show evil deeds to the wicked — evil deeds that those wicked people did not do. And when the wicked protest, "We did not commit these particular wicked deeds," the Heavenly Court will answer, "These sins were committed by those against whom you gossiped, and these sins have therefore been taken from them and added to yours." And this is the meaning of what is said: "And render unto our neighbors (who gossip against us) sevenfold into their bosom their reproach, wherewith they have reproached Thee, O Lord!" (Ps. 79:12). For anyone who reviles a righteous man, it is as though he reviles the Lord, Blessed be He. For the enemies of Israel are called the "enemies of God" in many places. And in connection with speaking against the righteous, the Torah has warned us: "Remember what the Lord your God did to Miriam on the journey …" (Deut. 24:9).
