Proverbs, I'm guessing. What chapter/s?27. The foolish man in company
does best if he stays silent;
no one will know that he knows nothing,
unless he talks too much;
but the man who knows nothing does not know
even if he is talking too much.
-Havamal, (Larrington 2014 translation)

6. About his intelligence no man should be boastful,
rather cautious of mind;
when a wise and silent man comes to a homestead
blame seldom befalls the wary;
for no more dependable friend can a man ever get
than a store of common sense.
7. The careful guest, who comes to a meal,
keeps silent, with hearing finely attuned;
he listens with his ears, and looks about with his eyes;
so every wise man spies out what’s ahead.
(also clearly not King James, so what version?)
