Basil of Caesarea, on Ps 33:13

“Who is the man that desireth life: who loveth to see good days?”

“The most common and varied sin is that committed through the tongue. Were you provoked to anger? The tongue is already running on. Are you possessed by concupiscence? Before all things you have a tongue, a sort of pimp and promoter, as it were, assistant to the sin, subduing your neighbors by histrionic arts. Your tongue is also a weapon for your injustice, not uttering the words from the heart but bringing forth those inspired by deceit. But what need is there to put in words all the sins committed through the tongue? Our life is filled with faults due to the tongue. Obscenity, scurrility, foolish talk, unbecoming words, slanders, idle conversation, perjuries, false testimony, all these evils, and even more than these, are the work of the tongue.”
