2 Chronicles 26:15

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, the first machines for throwing projectiles mentioned in history. And his name spread far abroad, and his power and authority at the same rate; for he was marvelously helped till he was strong. He conducted himself in everything as the representative of the Lord and was blessed by God accordingly. Before the Lord sends His judgments upon men, He often tries to have His goodness lead them to repentance.
