1 Samuel 13:19-22

19Now no blacksmith could be found throughout all the land of Israel, for the Philistines said, “Otherwise the Hebrews will make swords or spears!”

20So all the Israelites had to go down to the Philistines, each to sharpen his plowshare, his sickle, his axe or his hoe.

21The price of sharpening was two-thirds of a shekel for the plowshares, the sickles, the three-pronged forks or the axes, or to set the oxgoads.

22So it came about on the day of battle, there was no sword or spear to be found in the hand of any of the troops that were with Saul and Jonathan—only Saul and his son Jonathan had them.
