Love Ye Therefore the Stranger, For Ye Were Strangers

Sophocles, Oedipus at Colonus 562-568 (Theseus to Oedipus; tr. E.F. Watling):

I do not forget my own upbringing in exile,
like yours, and how many times I battled, alone,
with dangers to my life, in foreign lands.
I could not turn from any fellow-man,
coming as you come, or deny him help,
I know that I am man; in the day to come
my portion will be as yours, no more, no less.

... οἶδα γ᾽ αὐτὸς ὡς ἐπαιδεύθην ξένος,
ὥσπερ σύ, χὢς εἷς πλεῖστ᾽ ἀνὴρ ἐπὶ ξένης
ἤθλησα κινδυνεύματ᾽ ἐν τὠμῷ κάρᾳ·
ὥστε ξένον γ᾽ ἂν οὐδέν᾽ ὄνθ᾽, ὥσπερ σὺ νῦν,        565
ὑπεκτραποίμην μὴ οὐ συνεκσῴζειν· ἐπεὶ
ἔξοιδ᾽ ἀνὴρ ὢν χὤτι τῆς εἰς αὔριον
οὐδὲν πλέον μοι σοῦ μέτεστιν ἡμέρας.
