Wisdom strengtheneth the wise more than ten mighty men which are in the city.

Wesley's Notes

7:19 Strengthen - Supports him in, and secures him against troubles and dangers.

Jamieson-Fausset-Brown Bible Commentary

19. Hebrew, "The wisdom," that is, the true wisdom, religion (2Ti 3:15).

than ten mighty-that is, able and valiant generals (Ec 7:12; 9:13-18; Pr 21:22; 24:5). These "watchmen wake in vain, except the Lord keep the city" (Ps 127:1).

Matthew Henry's Concise Commentary

7:11-22 Wisdom is as good as an inheritance, yea better. It shelters from the storms and scorching heat of trouble. Wealth will not lengthen out the natural life; but true wisdom will give spiritual life, and strengthen men for services under their sufferings. Let us look upon the disposal of our condition as the work of God, and at last all will appear to have been for the best. In acts of righteousness, be not carried into heats or passions, no, not by a zeal for God. Be not conceited of thine own abilities; nor find fault with every thing, nor busy thyself in other men's matters. Many who will not be wrought upon by the fear of God, and the dread of hell, will avoid sins which ruin their health and estate, and expose to public justice. But those that truly fear God, have but one end to serve, therefore act steadily. If we say we have not sinned, we deceive ourselves. Every true believer is ready to say, God be merciful to me a sinner. Forget not at the same time, that personal righteousness, walking in newness of life, is the only real evidence of an interest by faith in the righteousness of the Redeemer. Wisdom teaches us not to be quick in resenting affronts. Be not desirous to know what people say; if they speak well of thee, it will feed thy pride, if ill, it will stir up thy passion. See that thou approve thyself to God and thine own conscience, and then heed not what men say of thee; it is easier to pass by twenty affronts than to avenge one. When any harm is done to us, examine whether we have not done as bad to others.
