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 plowshare, mattock, axe, and sickle; 21 yet they had a file for the mattocks, and for the plowshares, and for the forks, and for the axes, and to set the goads. 22 So 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 who were with Saul and Jonathan: but with Saul and with Jonathan his son was there found. 23 The garrison of the Philistines went out to the pass of Michmash.

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.
