Ye have heard, &c. Jesus now proceeds in his sermon to the seventh commandment, the true interpretation of which he gives us. Thou shalt not commit adultery This, as well as the sixth commandment, the scribes and Pharisees interpreted barely of the outward act. But I say unto you, &c. The command extends not only to unchaste actions and words, but even to looks, and the very thoughts of the heart: for whosoever looketh on a woman to lust after her Whosoever cherishes or indulges unchaste imaginations, desires, and intentions, hath committed adultery with her, &c. Hath been guilty of a violation of this commandment, which was intended to forbid the corrupt inclinations of the heart, and all irregular desires, as well as the pollution of the body.
