15 These two have I seen in my life which is to no purpose: a good man coming to his end in his righteousness, and an evil man whose days are long in his evil-doing. 16 Be not given overmuch to righteousness and be not over-wise. Why let destruction come on you? 17 Be not evil overmuch, and be not foolish. Why come to your end before your time? 18 It is good to take this in your hand and not to keep your hand from that; he who has the fear of God will be free of the two. 19 Wisdom makes a wise man stronger than ten rulers in a town. 20 There is no man on earth of such righteousness that he does good and is free from sin all his days. 21 Do not give ear to all the words which men say, for fear of hearing the curses of your servant. 22 Your heart has knowledge how frequently others have been cursed by you.

Commentary on Ecclesiastes 7:11-22
(Read Ecclesiastes 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.
