1 Samuel 13:19-21

19No blacksmith could be found in all the land of Israel because the Philistines had said, “Otherwise, the Hebrews will make swords or spears.”

20So all the Israelites went to the Philistines to sharpen their plows, mattocks, axes, and sickles.

21The price was two-thirds of a shekel for plows and mattocks, and one-third of a shekel for pitchforks and axes, and for putting a point on a cattle prod.
