Here we have, 1. The sins threatened--bearing false witness in judgment
and speaking lies in common conversation. Men could not arrive at such
a pitch of impiety as to bear false witness (where to the guilt of a
lie is added that of perjury and injury) if they had not advanced to it
by allowing themselves to speak untruths in jest and banter, or under
pretence of doing good. Thus men teach their tongues to speak lies,
Jer. ix. 5. Those that will take a liberty to tell lies in discourse
are in a fair way to be guilty of the greater wickedness of
false-witness-bearing, whenever they are tempted to it, though they
seemed to detest it. Those that can swallow a false word debauch their
consciences, so that a false oath will not choke them. 2. The
threatening itself: They shall not go unpunished; they shall not
escape. This intimates that that which emboldens them in the sin is the
hope of impunity, it being a sin which commonly escapes punishment from
men, though the law is strict, Deut. xix. 18, 19. But it shall not
escape the righteous judgment of God, who is jealous, and will not
suffer his name to be profaned; we know where all liars will have their
everlasting portion.
