1 Samuel 13
19 Ref Now there was no iron-worker in all the land of Israel: for the Philistines said, For fear the Hebrews make themselves swords or spears:
20 But all the Israelites had to go to the Philistines to get their ploughs and blades and axes and hooks made sharp;
21 For they had instruments for putting an edge on their ploughs and blades and forks and axes, and for putting iron points on their ox-driving rods.
22 Ref So on the day of the fight at Michmash, not a sword or a spear was to be seen in the hands of any of the people with Saul and Jonathan: only Saul and his son Jonathan had them.
