John Chrysostom
Catena Aurea · Matthäusevangelium 5
Ye have heard that it was said by them of old time, Thou shalt not commit adultery: But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
(Hom. xvii.) The Lord having explained how much is contained in the first commandment, namely, Thou shalt not kill, proceeds in regular order to the second.
