1 Samuel 13:19-22

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.
