This we had before (ch. xix. 25), and it shows that there are two ways
by which the simple may be made wise:--1. By the punishments that are
inflicted on those that are incorrigibly wicked. Let the law be
executed upon a scorner, and even he that is simple will be awakened
and alarmed by it, and will discern, more than he did, the evil of sin,
and will take warning by it and take heed. 2. By the instructions that
are given to those that are wise and willing to be taught: When the
wise is instructed by the preaching of the word he (not only the wise
himself, but the simple that stands by) receives knowledge. It is no
injustice at all to take a good lesson to ourselves which was designed
for another.
