John Lightfoot on Matthew 5:27

[Ye have heard, that it hath been said by them of old time, Thou shalt not commit adultery.] He citeth not the command or text of Moses, as barely delivered by Moses, but as deformed by those of old time with such a gloss as almost evacuated all the force of the command; for they interpreted it of the act of adultery only, and that with a married woman. So the enumeration of the six hundred and thirteen precepts of the law, and that, Exodus 20:14, 'Thou shalt not commit adultery,' hath these words, "This is the thirty-fifth precept of the law, namely, That no man lie with another man's wife."
