30 Then he took their king's crown from his head. Its weight was a talent of gold, with precious stones. And it was set on David's head. Also he brought out the spoil of the city in great abundance.
To be thus severe in putting the children of Ammon to slavery was a sign that David's heart was not yet made soft by repentance, at the time when this took place. We shall be most compassionate, kind, and forgiving to others, when we most feel our need of the Lord's forgiving love, and taste the sweetness of it in our own souls.
