2 Kings 18:8

He smote the Philistines, the ancient enemy of Judah on the west, even unto Gaza and the borders thereof, the southernmost of their city-states, from the tower of the watchmen to the fenced city, the smallest hamlet as well as the most strongly fortified town. When any person, especially, however, a mighty ruler, clings to the Lord with all faithfulness and does not forsake His ways, this is a great mercy of God.
