<p>"Listen, master, to what I am saying. Rest yourself from starting quarrels with your neighbors, and if you see something evil about your friend, do not produce their slander on your tongue."</p>
<p>This is the proverb of the letter Shin (ש) in the Alphabet of Ben Sira, and it's notable for a detail that's easy to miss. Ben Sira calls his teacher "master." He addresses him with respect. And then, like a child who's somehow older than the adult in the room, he tells the master exactly how to behave.</p>
<p>The advice comes in two parts. First, don't pick fights. Second, don't gossip. In Jewish tradition, lashon hara (לשון הרע) -- evil speech about others -- is treated as one of the most serious sins a person can commit. The Talmud in Arachin 15b compares gossip to murder, saying it kills three people: the speaker, the listener, and the subject. Ben Sira is drawing on that tradition, but with his usual directness.</p>
<p>What makes this proverb interesting is how it links quarreling and gossip as two sides of the same coin. You fight with someone, and then you talk about them behind their back. The Alphabet of Ben Sira, written between 700 and 1000 CE, recognized something modern psychology has confirmed. Conflict and gossip feed each other in a vicious cycle. Cut off one, and you weaken the other.</p>
<p>The cure, Ben Sira suggests, starts with the tongue. Control what you say, and you'll control what you do.</p>
