Warlike invention.

And Uzziah prepared for them throughout all the host shields, and spears, and helmets, and habergeons, and bows, and slings to cast stones. 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. ( 2 Chronicles 1:1 Galatians 26:14-15 )
