The Enemy of My Enemy Is My Friend

Aeschylus, Libation-Bearers 109-111 (tr. Alan H. Sommerstein):

                                      CHORUS
As you pour, speak good words for those who are friendly.

                                      ELECTRA
And which of those close to me should I designate in that way?

                                      CHORUS
In the first place yourself, and everyone who hates Aegisthus.

                                      ΧΟΡΟΣ
φθέγγου χέουσα κεδνὰ τοῖσιν εὔφροσιν.

                                      ΗΛΕΚΤΡΑ
τίνας δὲ τούτους τῶν φίλων προσεννέπω;

                                      ΧΟΡΟΣ
πρῶτον μὲν αὑτὴν χὤστις Αἴγισθον στυγεῖ.
