Whosoever knows how to render benefit for benefit must prove a friend above price.
ὅστις γὰρ εὖ δρᾶν εὖ παθὼν ἐπίσταται,
παντὸς γένοιτ᾿ ἂν κτήματος κρείσσων φίλος.
παντὸς γένοιτ᾿ ἂν κτήματος κρείσσων φίλος.
Original text (Ancient Greek)
More quotes by Sophocles
It is no weakness for the wisest man
To learn when he is wrong.
A prudent mind can see room for misgiving, lest he who prospers should one day suffer reverse.
When the mind hath once become a parent of evil, it teaches men to be evil thenceforth.
I well believe it, to unwilling ears;None love the messenger who brings bad news.
Evil seems good, soon or late, to him whose mind the god draws to mischief.
