The tongue of the wise useth knowledge aright; as the heart of a wise and good man is filled with useful knowledge, civil, moral, spiritual, and evangelical. The wise takes care to communicate knowledge at proper times and seasons, in proper places, and to proper persons; adapting it to their case and circumstances, so as it may be for their comfort, edification, and instruction, and minister grace unto them; which is using knowledge "well", as the word (s) signifies.
Such a use
of it recommends it, and makes it appear beautiful and lovely,
decorates and adorns it. Thus every good man, out of the good treasure
of knowledge in his heart, brings forth his good things seasonably, to
the use of edifying; in like manner, ministers of the word, scribes well
instructed in the things of God, bring forth both new and old, to the
profit of those to whom they minister; so Christ, as man and Mediator,
had the tongue of the learned, to speak a word in season to weary souls.
But the mouth of fools poureth out foolishness; their knowledge,
as they take it to be, but it is no other than folly; this they throw
out in great plenty, in a hurry, without fear or wit; they "babble" it
out, as the word (t) signifies, as water out of a fountain; their hearts
are full of it, and their mouths proclaim it.
