Pro 20:25 It is a snare to the man who devoureth that which is holy, and after vows to make enquiry.
Pro 20:26 A wise king scattereth the wicked, and bringeth the wheel over them.
Pro 20:27 The spirit of man is the candle of the LORD, searching all the inward parts of the belly.
Pro 20:28 Mercy and truth preserve the king: and his throne is upholden by mercy.
Pro 20:29 The glory of young men is their strength: and the beauty of old men is the gray head.
Pro 20:30 The blueness of a wound cleanseth away evil: so do stripes the inward parts of the belly.
The last verse is about how chastisement can heal evil. In my work as a volunteer leader, I see a lot of people unwilling to give their children consequences. They think I am mean if I do. In reality, consequences are far better as they get the attention of the person and drive home the point their behavior was or is not acceptable. They aren’t a bad thing at all.
