1 Samuel 13:19-22

19Now no blacksmith (metal-worker) could be found in all the land of Israel, for the Philistines said, “Otherwise the Hebrews will make swords or spears.”

20So all [the men of] Israel went down to the Philistines, each to get his plowshare, pick, axe, or sickle sharpened.

21The fee [for sharpening] was a pim (two-thirds of a shekel) for the plowshares, the picks, the pitchforks, and the axes, and to straighten the goads (cattle prods).

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