Some of his skilled workers invented machines that could shoot arrows and sling large stones. Uzziah set these up in Jerusalem at his defence towers and at the corners of the city wall. God helped Uzziah become more and more powerful, and he was famous all over the world.
He put a stone in his sling and swung the sling around by its straps. When he let go of one strap, the stone flew out and hit Goliath on the forehead. It cracked his skull, and he fell face down on the ground.
