1 Samuel 13:21

19Now there was no blacksmith found throughout all the land of Israel, for the Philistines said, “Lest the Hebrews make themselves swords or spears”;

20but all the Israelites went down to the Philistines, each man to sharpen his own plowshare, mattock, ax, and sickle.

21The price was one payim each to sharpen mattocks, plowshares, pitchforks, axes, and goads.

22So it came to pass in the day of battle that neither sword nor spear was found in the hand of any of the people who were with Saul and Jonathan; but Saul and Jonathan his son had them.

23The garrison of the Philistines went out to the pass of Michmash.
