2 Chronicles 26:15

And in Jerusalem he made skillfully designed devices to shoot arrows and catapult large stones from the towers and corners. So his fame spread far and wide, for he was helped tremendously until he became powerful.

And he made in Jerusalem engines, invented by cunning men, to be on the towers and upon the bulwarks, to shoot arrows and great stones withal. And his name spread far abroad; for he was marvellously helped, till he was strong.
