Good governance is active — the wise king does not passively allow wickedness to accumulate but scatters it and threshes it out. The 'wheel' is a threshing wheel, separating grain from chaff. Righteous leadership involves vigorous action against evil for the protection of the innocent.
Memory phrase: Wise leaders fight against evil.
Talk about it: What does a good leader do when they see something wrong?
Prayer: God, give us wise leaders who drive away evil.
