1 Samuel 13
19 Ref 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 set the goads.
