1 Samuel 13:16-20

Now Saul, his son Jonathan, and the people who were present with them were staying in Geba of Benjamin while the Philistines camped at Michmash.

Then raiders came from the camp of the Philistines in three companies: one company turned toward Ophrah, to the land of Shual,

and another company turned toward Beth-horon, and another company turned toward the border that overlooks the Valley of Zeboim toward the wilderness.

Now no blacksmith could be found in all the land of Israel, because the Philistines said, “Otherwise the Hebrews will make swords or spears.”

So all Israel went down to the Philistines, each to sharpen his plowshare, his mattock, his axe, and his hoe.
