19 Now there was no smith to be found throughout all the land of Israel; for the Philistines said, "Lest the Hebrews make themselves swords or spears"; 20 but every one of the Israelites went down to the Philistines to sharpen his plowshare, his mattock, his axe, or his sickle; 21 and the charge was a pim for the plowshares and for the mattocks, and a third of a shekel for sharpening the axes and for setting the goads. 22 So on the day of the battle there was neither sword nor spear found in the hand of any of the people with Saul and Jonathan; but Saul and Jonathan his son had them.
Matthew Henry's Commentary on 1 Samuel 13:19-22
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.
