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.
(cont. Faust. xix. 23.) He then goes on to correct the error of the Pharisees, declaring, Whoso looketh upon a woman to lust after her, hath committed adultery already with her in his heart. For the commandment of the Law, Thou shall not lust after thy neighbour’s wife, (Exod. 20:17.) the Jews understood of taking her away, not of committing adultery with her.
