ὡς οὐκ ἔστι λέουσι καὶ ἀνδράσιν ὅρκια πιστά,
οὐδὲ λύκοι τε καὶ ἄρνες ὁμόφρονα θυμὸν ἔχουσιν,
ἀλλὰ κακὰ φρονέουσι διαμπερὲς ἀλλήλοισιν

or, the exact translation;

As there can be no covenants between men and lions,
neither can wolves and lambs ever be of one mind,
but hate each other for ever and ever.

whoever knew Greek literature was so interesting =P all the memorized names of books we did in Form 3 is interesting after all.
