“We have here an exposition of the seventh commandment, given us by the same hand that made the law, and therefore was fittest to be the interpreter of it... The command is here laid down 'Thou shalt not commit adultery;' which includes a prohibition of all other acts of uncleanness, and the desire of them: but the Pharisees, in their expositions of this command, made it to extend no further than the act of adultery, suggesting, that if the iniquity was only regarded in the heart, and went no further, God could not hear it, would not regard it, and therefore they thought it enough to be able to say that they were 'not adulterers' (Luke 18:11).” -Matthew Henry
