Note, 1. Those that have power are apt to promise themselves great things from their power. The city of the mighty thinks itself impregnable, and therefore its strength is the confidence thereof, what it boasts of and trust in, bidding defiance to danger. 2. Those that have wisdom, though they are so modest as not to promise much, often perform great things, even against those that are so confident of their strength, by their wisdom. Good conduct will go far even against great force; and a stratagem, well managed, may effectually scale the city of the mighty and cast down the strength it had such a confidence in. A wise man will gain upon the affections of people and conquer them by strength of reason, which is a more noble conquest than that obtained by strength of arms. Those that understand their interest will willingly submit themselves to a wise and good man, and the strongest walls shall not hold out against him.

A wise man scaleth the city of the mighty,.... Which makes good what is elsewhere said, that "wisdom is better than strength", Ecc 9:16; and sometimes more is done by prudence and wisdom, by art and cunning, by schemes and stratagems, than by power and force; especially in military affairs, and particularly in besieging and taking fortified cities; when one wise man, by his wisdom, may so order and manage things, as to be able, with a few under his command, to mount the walls of a city and take it, though defended by a mighty garrison in it. This may be applied to, our Lord Jesus Christ entering into the city of a man's heart, possessed by the strong man armed; overcoming him, taking from him his armour, and dividing his spoil, Luk 11:21; compare with this Ecc 9:14;

and casteth down the strength of the confidence thereof; the strong walls, bulwarks, and such fortifications, in which the mighty in the city placed their confidence: and the like does Christ, when he enters into the heart of a sinner by his word and spirit; he destroys all its former strong confidences, and brings it into subjection to himself, Co2 10:4.

"Wisdom is better than strength" (Ecc 7:19; Ecc 9:15).

strength . . . thereof--that in which they confide.
