Sinner - The word in the original indicates intellectual as well as moral error.

Wisdom is better than weapons of war - So proved in the case of Archimedes.

But one sinner - Such as the Roman butcher above mentioned.

Destroyeth much good - Such as were the life and skill of the Syracusan mathematician. One sinner has often injured the work of God; one stumbling-block has sometimes destroyed a revival of religion. Sin acts like a ferment; whatever comes in contact with it, it assimilates to itself.

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".

The following proverb also leans on the history above narrated: "Better is wisdom than weapons of war; and one sinner destroyeth much good." The above history has shown by way of example that wisdom accomplishes more than implements of war, כּלי ק equals כּלי מל (Assyr. unut tahazi)

(Note: Vid., Fried. Delitzsch's Assyr. Stud. p. 129.)

i.e., than all the apparatus belonging to preparation for war. But the much good which a wise man is accomplishing or has accomplished, one sinner (חוטא)

(Note: The Syr. (not the Targ.) had חטא before it, and thus realized it, which appears to correspond better with the parall. חכמה.)

by treachery or calumny may render vain, or may even destroy, through mere malicious pleasure in evil. This is a synthetic distich whose two parts may be interpreted independently. As wisdom accomplishes something great, so a single villain may have a far-reaching influence, viz., such as destroys much good.

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

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).

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.
