Proverbs 20:28

It is a snare to a man to make a rash dedication,

then later to consider his vows.

A wise king winnows out the wicked,

and drives the threshing wheel over them.

The spirit of man is the LORD’s lamp,

searching all his innermost parts.

The glory of young men is their strength.

The splendor of old men is their gray hair.

Wounding blows cleanse away evil,

and beatings purge the innermost parts.
