1 Samuel 13:16-23

16And Saul, and Jonathan his son, and the people that were found with them, abode in Geba of Benjamin; and the Philistines encamped in Michmash. 17And the ravagers came out of the camp of the Philistines in three companies: one company turned the way of Ophrah, into the land of Shual; 18and another company turned the way to Beth-horon; and the other company turned the way to the district that looks over the ravine of Zeboim toward the wilderness. 19Now there was no smith found throughout the land of Israel; for the Philistines said, Lest the Hebrews make them swords or spears. 20And all Israel went down to the Philistines, every man to get his ploughshare, and his hoe, and his axe, and his sickle sharpened, 21when the edges of the sickles, and the hoes, and the forks, and the axes were blunted; and to set the goads. 22And it came to pass in the day of battle, that there was neither sword nor spear found in the hand of any of the people that were with Saul and Jonathan; but with Saul and with Jonathan his son there was found. 23And a garrison of the Philistines went out to the passage of Michmash.
