9:13-18 A man may, by his wisdom, bring to pass that which he could never do by his strength. If God be for us, who can be against us, or stand before us? Solomon observes the power of wisdom, though it may labour under outward disadvantages. How forcible are right words! But wise and good men must often content themselves with the satisfaction of having done good, or, at least, endeavoured to do it, when they cannot do the good they would, nor have the praise they should. How many of the good gifts, both of nature and Providence, does one sinner destroy and make waste! He who destroys his own soul destroys much good. One sinner may draw many into his destroying ways. See who are the friends and enemies of a kingdom or a family, if one saint does much good, and one sinner destroys much good.Sinner - The word in the original indicates intellectual as well as moral error. 18. one sinner, &c.—(Jos 7:1, 11, 12). Though wisdom excels folly (Ec 9:16; 7:19), yet a "little folly (equivalent to sin) can destroy much good," both in himself (Ec 10:1; Jas 2:10) and in others. "Wisdom" must, from the antithesis to "sinner," mean religion. Thus typically, the "little city" may be applied to the Church (Lu 12:32; Heb 12:22); the great king to Satan (Joh 12:31); the despised poor wise man, Jesus Christ (Isa 53:2, 3; Mr 6:3; 2Co 8:9; Eph 1:7, 8; Col 2:3). Than weapons of war; than armed power.

Sinner; a wicked fool; by which expression and opposition of a sinner to a wise man he gives us a key to understand his meaning in divers places of his books, that by wisdom he means true piety, and by folly wickedness; and withal, showeth that sin, as it is the greatest folly, so it is more pernicious to men than mere folly properly so called.

Destroyeth much good; by his wicked counsels and courses brings much damage and mischief, both to himself and others.

Wisdom is better than weapons of war,.... And does what they cannot do; of which the wisdom of the poor wise man is a full proof, which delivered the city from a potent prince, when weapons of war could not: see Ecclesiastes 7:10;

but one sinner destroyeth much good: his own soul by his sins, and the souls of others by his counsels, example, and conversation, which corrupt good manners; so does one sinner in a family, neighbourhood, and town; as one poor wise man does much good, one sinner mars much; one Achan in a camp or army, one bad counsel for in a cabinet, one false teacher in the church, will do a great deal of mischief, as well as one debauchee in a town or city. The Vulgate Latin version is, "who sins in one"; offends or sins in one, as in James 2:10; so the Syriac version, "one sin destroys much good", or many good things; and to the same purpose the Arabic version, "he that committeth one sin".

Wisdom is better than weapons of war: but one sinner destroyeth much good.
