The ears and mouths of the wise and the foolish

Here are some contrasts between the wise and the foolish concerning the use of their ears and mouths. The wise are teachable and listen to Godly correction. The foolish will not listen to a rebuke. The wise know when to restrain their words and are able to do so. And as a result they protect themselves. The foolish don't hold back their tongue and bring ruin upon themselves.
