Happy New Year to you!

This would be "ΣΙΩΠΗΣΤΕ" (σιωπήστε). Masculine is of no importance in the imperative case.

The original verb is "ΣΙΩΠΑΩ → ΣΙΩΠΩ" meaning "keep silent".

Ἦγε δὲ καὶ τὸν δῆμον τῶν Ῥωμαίων ἐμβριθῶς μᾶλλον ἢ θωπευτικῶς· καί ποτε ἰσχυρῶς αἰτοῦντί τι ἐν ὁπλομαχίᾳ οὔτε ἔνειμε, καὶ προσέτι ἐκέλευσε τοῦτο δὴ τὸ τοῦ Δομιτιανοῦ κηρυχθῆναι “σιωπήσατε.” οὐκ ἐλέχθη μὲν γάρ· ὁ γὰρ κῆρυξ ἀνατείνας τὴν χεῖρα καὶ ἐξ αὐτοῦ τούτου3 ἡσυχάσας, ὥσπερ εἰώθασι ποιεῖν (οὐ γὰρ ἔστιν ὁπότε ὑπὸ κηρύγματος σιγάζονται), ἐπειδὴ ἐσιώπησαν, ἔφη “τοῦτ᾿ ἐθέλει.” καὶ οὐκ ὅτι τινὰ ὀργὴν τῷ κήρυκι ἔσχεν, ἀλλὰ καὶ ἐτίμησεν αὐτὸν ὅτι τὴν δυσχέρειαν τοῦ κελεύσματος οὐκ ἐξέφησεν. ἔφερε γὰρ τὰ τοιαῦτα, καὶ οὐκ ἠγανάκτει εἴ τι καὶ παρὰ γνώμην καὶ πρὸς τῶν τυχόντων ὠφελοῖτο. ἀμέλει γυναικὸς παριόντος αὐτοῦ ὁδῷ τινι δεομένης, τὸ μὲν πρῶτον εἶπεν αὐτῇ ὅτι “οὐ σχολάζω,” ἔπειτα ὡς ἐκείνη ἀνακραγοῦσα

For he could bear such things, and was not displeased if he received aid either in an unexpected way or from ordinary men.
