19 Now there was no smith to be found throughout all the land of Israel; for the Philistines said, "The Hebrews must not make swords or spears for themselves"; 20 so all the Israelites went down to the Philistines to sharpen their plowshares, mattocks, axes, or sickles; 21 The charge was two-thirds of a shekel for the plowshares and for the mattocks, and one-third of a shekel for sharpening the axes and for setting the goads. 22 So on the day of the battle neither sword nor spear was to be found in the possession of any of the people with Saul and Jonathan; but Saul and his son Jonathan had them.

Commentary on 1 Samuel 13:15-23
(Read 1 Samuel 13:15-23)
See how politic the Philistines were when they had power; they not only prevented the people of Israel from making weapons of war, but obliged them to depend upon their enemies, even for instruments of husbandry. How impolitic Saul was, who did not, in the beginning of his reign, set himself to redress this. Want of true sense always accompanies want of grace. Sins which appear to us very little, have dangerous consequences. Miserable is a guilty, defenceless nation; much more those who are destitute of the whole armour of God.
