The tree is known by its fruits, a man by his doings, even a young tree
by its first fruits, a child by his childish things, whether his work
be clean only, appearing good (the word is used ch. xvi. 2), or whether
it be right, that is, really good. This intimates, 1. That children
will discover themselves. One may soon see what their temper is, and
which way their inclination leads them, according as their constitution
is. Children have not learned the art of dissembling and concealing
their bent as grown people have. 2. That parents should observe their
children, that they may discover their disposition and genius, and both
manage and dispose of them accordingly, drive the nail that will go and
draw out that which goes amiss. Wisdom is herein profitable to direct.
