22 Understanding is a wellspring of life unto him that hath it: but the instruction of fools is folly.
Note, 1. There is always some good to be gotten by a wise and good man: His understanding is a well-spring of life to him, which always flows and can never be drawn dry; he has something to say upon all occasions that is instructive, and of use to those that will make use of it, things new and old to bring out of his treasure; at least, his understanding is a spring of life to himself, yielding him abundant satisfaction; within his own thoughts he entertains and edifies himself, if not others. 2. There is nothing that is good to be gotten by a fool. Even his instruction, his set and solemn discourses, are but folly, like himself, and tending to make others like him. When he does his best it is but folly, in comparison even with the common talk of a wise man, who speaks better at table than a fool in Moses's seat.
