1 Samuel 13:19-23

19Now there was no blacksmith to be found throughout all the land of Israel, for the Philistines said, “Lest the Hebrews make themselves swords or spears.” 20But every one of the Israelites went down to the Philistines to sharpen his plowshare, his mattock, his axe, or his sickle, 21and the charge was two-thirds of a shekel for the plowshares and for the mattocks, and a third of a shekel for sharpening the axes and for setting the goads. 22So on the day of the battle there was neither sword nor spear found in the hand of any of the people with Saul and Jonathan, but Saul and Jonathan his son had them. 23And the garrison of the Philistines went out to the pass of Michmash.
