1 Samuel 13:19-21

Now no blacksmith could be found in all the land of Israel, for the Philistines said, “Otherwise the Hebrews will make swords or spears.” So all Israel went down to the Philistines, each to sharpen his plowshare, his mattock, his axe, and his hoe. The charge was two-thirds of a shekel for the plowshares, the mattocks, the forks, and the axes, and to fix the hoes.
