The inclusion of this proverb, which is about the justice of the Lord, shows that it is right to see in the surrounding proverbs, which also speak of the ways of kings, a reference to the Lord as King of kings.A trader used to carry around with him in his bag a set of stones which were used as weights in measuring out what he bought and sold.
When we seek guidance from the Lord, we must be careful of small compromises. Are we constantly looking to shave time off our service for the Lord, or to cut corners on the tasks that we have been given to do, or to keep back some of what we have stewarded to the Lord? No, we must do the opposite and always go the extra mile with the Lord in all our service to him.
