Wisdom and the fool.
v.1 The wise woman. A wise woman brings prosperity to her household, but a foolish woman tears hers down with her own hands.
v.2 Fear of the Lord. The upright in walk fear the Lord, but the devious in his ways despises him.
v.3 The fools talk. The speech of the righteous brings safety (protection from needless pain). The talk of the fool brings punishment (a rod for his back).
v.4 The fool has no ox. The manger is clean where there are no oxen, but the strength of an ox brings abundant harvest. One must have oxen to produce crops. Although a farmer can save some work and expense by not having oxen, the benefit of keeping oxen far exceeds the cost.
v.5 A faithful witness. A faithful witness does not lie, but a false witness pours out lies (and does great harm). See 19:28.
v.6 Who finds wisdom. The mocker seeks (superficially) for wisdom but cannot find it. Wisdom comes easy for a man of understanding (who is open to correction, displays humility, and fears the Lord).
v.7 A foolish man. Don’t associate with the foolish man, knowledge is not found there. See 13:20.
The wise and foolish are contrasted in these proverbs. To follow the path of the wise, keep away from the company of fools. The upright walk in fear of God, don’t try to “go it alone” in life.
