In Jerusalem Uzziah made cleverly designed devices. These devices on the towers and corners of the city walls were used to shoot arrows and large rocks. So Uzziah became famous in faraway places, because he had much help until he became powerful.
He took a stone from his bag, put it into his sling, and slung it. The stone hit the Philistine and went deep into his forehead, and Goliath fell facedown on the ground.
