Ecc 9:18
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 = כּלי מל (Assyr. unut tahazi)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) 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.
