1 Samuel 13:19

¹⁷  And the spoilers came out of the camp of the Philistines in three companies: one company turned unto the way that leadeth to Ophrah, unto the land of Shual:

¹⁸  And another company turned the way to Bethhoron: and another company turned to the way of the border that looketh to the valley of Zeboim toward the wilderness.

¹⁹  Now there was no smith found throughout all the land of Israel: for the Philistines said, Lest the Hebrews make them swords or spears:

²⁰  But all the Israelites went down to the Philistines, to sharpen every man his share, and his coulter, and his axe, and his mattock.

²¹  Yet they had a file for the mattocks, and for the coulters, and for the forks, and for the axes, and to sharpen the goads.
