φιλεῖ δὲ σιγᾶν ἢ λέγειν τὰ καίρια.

More quotes by Aeschylus
Only when man's life comes to its end in prosperity can one call that man happy.
It is not the oath that makes us believe the man, but the man the oath.

To sin by silence, when we should protest,
Makes cowards out of men.
Blessed is the man who, having nothing to say, abstains from giving us wordy evidence of the fact.
There are times when good words are to be left unsaid out of esteem for silence.
