'Commit Adultery' in the Bible

thou that sayest man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?

For, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not lust; and if there be any other commandment, it is summed up in this word, namely, Thou shalt love thy neighbour as thyself.
