1 Samuel 13:19-22

19Not a blacksmith could be found in the whole land of Israel, because the Philistines had said, “Otherwise the Hebrews will make swords or spears!” 20So all Israel went down to the Philistines to have their plow points, mattocks, axes and sickles sharpened. 21The price was two-thirds of a shekel for sharpening plow points and mattocks, and a third of a shekel for sharpening forks and axes and for repointing goads. 22So on the day of the battle not a soldier with Saul and Jonathan had a sword or spear in his hand; only Saul and his son Jonathan had them.
