1 Samuel 13:15-22

And Samuel arose and went up from Gilgal. The rest of the people went up after Saul to meet the army; they went up from Gilgal to Gibeah of Benjamin. And Saul numbered the people who were present with him, about six hundred men. And Saul and Jonathan his son and the people who were present with them stayed in Geba of Benjamin, but the Philistines encamped in Michmash. And raiders came out of the camp of the Philistines in three companies. One company turned toward Ophrah, to the land of Shual; another company turned toward Beth-horon; and another company turned toward the border that looks down on the Valley of Zeboim toward the wilderness. Now 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.” But every one of the Israelites went down to the Philistines to sharpen his plowshare, his mattock, his axe, or his sickle, and 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. So 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.
