I made a covenant with mine eyes; How then should I look upon a virgin?

I made an agreement with my eyes; how then might my eyes be looking on a virgin?

Εκαμον συνθηκην μετα των οφθαλμων μου· και πως να εχω τον στοχασμον μου επι παρθενον;

I made a covenant with mine eyes; why then should I think upon a maid?
