See here, 1. How much praise is due to a faithful witness: He delivers
the souls of the innocent, who are falsely accused, and their good
names, which are as dear to them as their lives. A man of integrity
will venture the displeasure of the greatest, to bring truth to light
and rescue those who are injured by falsehood. A faithful minister, who
truly witnesses for God against sin, is thereby instrumental to deliver
souls from eternal death. 2. How little regard is to be had to a false
witness. He forges lies, and yet pours them out with the greatest
assurance imaginable for the destruction of the innocent. It is
therefore the interest of a nation by all means possible to detect and
punish false-witness-bearing, yea, and lying in common conversation;
for truth is the cement of society.
