This has nothing to do with Treason.
Plutarch, On Talkativeness, 505a-b
“Some of the other faults and disorders we suffer are dangerous, hateful, or absurd; but talkativeness is all of these things. For chatterboxes are mocked for explaining common affairs, hated for trumpeting bad news, and they risk their lives because they can’t keep secrets.
For this reason, when Anacharsis had a feast at Solon’s home and was stretched out to sleep, he covered his genitals with his left hand and placed his right hand over his mouth: he thought that the tongue demanded the stronger protection! And this is correct. For, one couldn’t easily make a list of how many men have been laid low because of uncontrolled lust any more than the number of cities and governments which a revealed secret has destroyed.”
Τῶν δ᾿ ἄλλων παθῶν καὶ νοσημάτων τὰ μέν ἐστιν ἐπικίνδυνα τὰ δὲ μισητὰ τὰ δὲ καταγέλαστα, τῇ δ᾿ ἀδολεσχίᾳ πάντα συμβέβηκε· χλευάζονται μὲν γὰρ ἐν ταῖς κοιναῖς διηγήσεσι, μισοῦνται δὲ διὰ τὰς τῶν κακῶν προσαγγελίας, κινδυνεύουσι δὲ τῶν ἀπορρήτων μὴ κρατοῦντες. ὅθεν Ἀνάχαρσις ἑστιαθεὶς παρὰ Σόλωνι καὶ κοιμώμενος ὤφθη τὴν μὲν ἀριστερὰν χεῖρα τοῖς μορίοις τὴν δὲ δεξιὰν τῷ στόματι προσκειμένην ἔχων· ἐγκρατεστέρου γὰρ ᾤετο χαλινοῦ δεῖσθαι τὴν γλῶτταν, ὀρθῶς οἰόμενος. οὐ γὰρ ἄν τις ἐξαριθμήσαιτο ῥᾳδίως ἄνδρας τοσούτους ἀφροδισίων ἀκρασίᾳ πεπτωκότας, ὅσας πόλεις καὶ ἡγεμονίας λόγος ἐξενεχθεὶς ἀπόρρητος ἀναστάτους ἐποίησε.
I hear the secrets that you keep, when you’re talking in your sleep
