Here is, 1. The character of a fool: He trusts to his own heart, to his
own wisdom and counsels, his own strength and sufficiency, his own
merit and righteousness, and the good opinion he has of himself; he
that does so is a fool, for he trusts to that, not only which is
deceitful above all things (Jer. xvii. 9), but which has often deceived
him. This implies that it is the character of a wise man (as before, v.
25) to put his trust in the Lord, and in his power and promise, and to
follow his guidance, Prov. iii. 5, 6. 2. The comfort of a wise man: He
that walks wisely, that trusts not to his own heart, but is humble and
self-diffident, and goes on in the strength of the Lord God, he shall
be delivered; when the fool, that trusts in his own heart, shall be
destroyed.
