So it came to pass in the day of battle, that there was neither {n} 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 was there found.

(n) To declare that the victory only came from God, and not by their force.

Wesley's Notes

13:22 Sword - It seems restrained to the six hundred that were with Saul and Jonathan; for there were no doubt a considerable number of swords and spears among the Israelites, but they generally hid them, as now they did their persons, from the Philistines. And the Philistines had not yet attained to so great a power over them, as wholly to disarm them, but thought it sufficient to prevent the making of new arms; knowing that the old ones would shortly be decayed, and useless. There were likewise other arms more common in those times and places, than swords and spears; to wit, bows and arrows, and slings and stones.

Matthew Henry's Concise Commentary

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.

Matthew Henry's Whole Bible Commentary

Verses 15-23

Here, 1. Samuel departs in displeasure. Saul has set up for himself, and now he is left to himself: Samuel gat him from Gilgal (v. 15), and it does not appear that he either prayed with Saul or directed him. Yet in going up to Gibeah of Benjamin, which was Saul's city, he intimated that he had not quite abandoned him, but waited to do him a kindness another time. Or he went to the college of the prophets there, to pray for Saul when he did not think fit to pray with him. 2. Saul goes after him to Gibeah, and there musters his army, and finds his whole number to be but 600 men, v. 15, 16. Thus were they for their sin diminished and brought low. 3. The Philistines ravage the country, and put all the adjacent parts under contribution. The body of their army, or standing camp (as it is called in the margin, v. 23), lay in an advantageous pass at Michmash, but thence they sent out three separate parties or detachments that took several ways, to plunder the country, and bring in provisions for the army, v. 17, 18. By these the land of Israel was both terrified and impoverished, and the Philistines were animated and enriched. This the sin of Israel brought upon them, Isa. 42:24. 4. The Israelites that take the field with Saul are unarmed, having only slings and clubs, not a sword or spear among them all, except what Saul and Jonathan themselves have, v. 19, 22. See here, (1.) How politic the Philistines were, when they had power in their hands, and did what they pleased in Israel. They put down all the smiths' shops, transplanted the smiths into their own country, and forbade any Israelite, under severe penalties, to exercise the trade or mystery of working in brass or iron, though they had rich mines of both (Deu. 8:9) in such plenty that it was said of Asher, his shoes shall be iron and brass, Deu. 33:25. This was subtilely done of the Philistines, for hereby they not only prevented the people of Israel from making themselves weapons of war (by which they would be both disused to military exercises and unfurnished when there was occasion), but obliged them to a dependence upon them even for the instruments of husbandry; they must go to them, that is, to some or other of their garrisons, which were dispersed in the country, to have all their iron-work done, and no more might an Israelite do than use a file (v. 20, 21), and no doubt the Philistines' smiths brought the Israelites long bills for work done. (2.) How impolitic Saul was, that did not, in the beginning of his reign, set himself to redress this grievance. Samuel's not doing it was very excusable; he fought with other artillery; thunder and lightning, in answer to his prayer, were to him instead of sword and spear; but for Saul, that pretended to be a king like the kings of the nations, to leave his soldiers without swords and spears, and take no care to provide them, especially when he might have done it out of the spoils of the Ammonites whom he conquered in the beginning of his reign, was such a piece of negligence as could by no means be excused. (3.) How slothful and mean-spirited the Israelites were, that suffered the Philistines thus to impose upon them and had no thought nor spirit to help themselves. It was reckoned very bad with them when there was not a shield or spear found among 40,000 in Israel (Jdg. 5:8), and it was not better now, when there was never an Israelite with a sword by his side but the king and his son, never a soldier, never a gentleman; surely they were reduced to this, or began to be so, in Samuel's time, for we never find him with sword or spear in his hand. If they had not been dispirited, they could not have been disarmed, but it was sin that made them naked to their shame.
