It was not long ago that the Philistines were soundly beaten, and put to the worse, before Israel, and they would have been totally routed if Saul's rashness had not prevented; but here we have them making head again. Observe,

I.How they defied Israel with their armies, Sa1 17:1. They made a descent upon the Israelites' country, and possessed themselves, as it should seem, of some part of it, for they encamped in a place which belonged to Judah. Israel's ground would never have been footing for Philistine-armies if Israel had been faithful to their God. The Philistines (it is probable) had heard that Samuel had fallen out with Saul and forsaken him, and no longer assisted and advised him, and that Saul had grown melancholy and unfit for business, and this news encouraged them to make this attempt for the retrieving of the credit they had lately lost. The enemies of the church are watchful to take all advantages, and they never have greater advantages than when her protectors have provoked God's Spirit and prophets to leave them. Saul mustered his forces, and faced them, Sa1 17:2, Sa1 17:3. And here we must take notice, 1. That the evil spirit, for the present, had left Saul, Sa1 16:23. David's harp having given him some relief, perhaps the alarms and affairs of the war prevented the return of the distemper. Business is a good antidote against melancholy. Let the mind have something without to fasten on and employ itself about, and it will be the less in danger of preying upon itself. God, in mercy to Israel, suspended the judgment for a while; for how distracted must the affairs of the public have been if at this juncture the prince had been distracted! 2. That David for the present had returned to Bethlehem, and had left the court, Sa1 17:15. When Saul had no further occasion to use him for the relief of his distemper, though, being anointed, he had a very good private reason, and, having a grant of the place of Saul's armour-bearer, he had a very plausible pretence to have continued his attendance, as a retainer to the court, yet he went home to Bethlehem, and returned to keep his father's sheep; this was a rare instance, in a young man that stood so fair for preferment, of humility and affection to his parents. He knew better than most do how to come down again after he had begun to rise, and strangely preferred the retirements of the pastoral life before all the pleasures and gaieties of the court. None more fit for honour than he, nor that deserved it better, and yet none more dead to it.

II.How they defied Israel with their champion Goliath, whom they were almost as proud of as he was of himself, hoping by him to recover their reputation and dominion. Perhaps the army of the Israelites was superior in number and strength to that of the Philistines, which made the Philistines decline a battle, and stand at bay with them, desiring rather to put the issue upon a single combat, in which, having such a champion, they hoped to gain the victory. Now concerning this champion observe,

1.His prodigious size. He was of the sons of Anak, who at Gath kept their ground in Joshua's time (Jos 11:22), and kept up a race of giants there, of which Goliath was one, and, it is probable, one of the largest. He was in height six cubits and a span, v. 4. They learned bishop Cumberland has made it out that the scripture-cubit was above twenty-one inches (above three inches more than our half-yard) and a span was half a cubit, by which computation Goliath wanted but eight inches of four yard in height, eleven feet and four inches, a monstrous stature, and which made him very formidable, especially if he had strength and spirit proportionable.

2.His armour. Art, as well as nature, made him terrible. He was well furnished with defensive armour (Sa1 17:5, Sa1 17:6): A helmet of brass on his head, a coat of mail, made of brass plates laid over one another, like the scales of a fish; and, because his legs would lie most within the reach of an ordinary man, he wore brass boots, and had a large corselet of brass about his neck. The coat is said to weigh 5000 shekels, and a shekel was half an ounce avoirdupois, a vast weight for a man to carry, all the other parts of his armour being proportionable. But some think it should be translated, not the weight of the coat, but the value of it, was 5000 shekels; so much it cost. His offensive weapons were extraordinary, of which his spear only is here described, Sa1 17:7. It was like a weaver's beam. His arm could manage that which an ordinary man could scarcely heave. His shield only, which was the lightest of all his accoutrements, was carried before him by his esquire, probably for state; for he that was clad in brass little needed a shield.

3.His challenge. The Philistines having chosen him for their champion, to save themselves from the hazard of battle, he here throws down the gauntlet, and bids defiance to the armies of Israel, Sa1 17:8-10. He came into the valley that lay between the camps, and, his voice probably being as much stronger than other people's as his arm was, he cried so as to make them all hear him, Give me a man, that we may fight together. He looked upon himself with admiration, because he was so much taller and stronger than all about him; his heart (says bishop Hall) nothing but a lump of proud flesh. He looked upon Israel with disdain, because they had none among them of such a monstrous bulk, and defies them to find a man among them bold enough to enter the list with him. (1.) He upbraids them with their folly in drawing an army together: "Why have you come to set the battle in array? How dare you oppose the mighty Philistines?" Or, "Why should the two armies engage, when the controversy may be sooner decided, with only the expense of one life and the hazard of another?" (2.) He offers to put the war entirely upon the issue of the duel he proposes: "If your champion kill me, we will be your servants; if I kill him, you shall be ours." This, says bishop Patrick, was only a bravado, for no nation would be willing thus to venture its all upon the success of one man, nor is it justifiable; notwithstanding Goliath's stipulation here, when he was killed the Philistines did not stand to his word, nor submit themselves as servants to Israel. When he boasts, I am a Philistine, and you are servants to Saul, he would have it thought a great piece of condescension in him, who was a chief ruler, to enter the lists with an Israelite; for he looked on them as no better than slaves. The Chaldee paraphrase brings him in boasting that he was the man that had killed Hophni and Phinehas and taken the ark prisoner, but that the Philistines had never given him so much as the command of a regiment in recompence of his services, whereas Saul had been made king for his services: "Let him therefore take up the challenge."

4.The terror this struck upon Israel: Saul and his army were greatly afraid, Sa1 17:11. The people would not have been dismayed but that they observed Saul's courage failed him; and it is not to be expected that, if the leader be a coward, the followers should be bold. We found before, when the Spirit of the Lord came upon Saul (Sa1 11:6), none could be more daring nor forward to answer the challenge of Nahash the Ammonite, but now that the Spirit of the Lord had departed from him even the big looks and big words of a single Philistine make him change colour. But where was Jonathan all this while? Why did not he accept the challenge, who, in the last war, had so bravely engaged a whole army of Philistines? Doubtless he did not feel himself stirred up of God to it, as he did in the former case. As the best, so the bravest men, are no more than what God makes them. Jonathan must now sit still, because the honour of engaging Goliath is reserved for David. In great and good actions, the wind of the Spirit blows when and where he listeth. Now the pious Israelites lament their king's breach with Samuel.

The staff on his spear was like a weaver's beam - Either like that on which the warp is rolled, or that on which the cloth is rolled. We know not how thick this was, because there were several sorts of looms, and the sizes of the beams very dissimilar. Our woollen, linen, cotton, and silk looms are all different in the size of their beams; and I have seen several that I should not suppose too thick, though they might be too short, for Goliath's spear.

His spear's head weighed six hundred shekels of iron - That is, his spear's head was of iron, and it weighed six hundred shekels; this, according to the former computation, would amount to eighteen pounds twelve ounces.

And one bearing a shield - הצנה hatstsinnah, from צן tsan, pointed or penetrating, if it do not mean some kind of a lance, must mean a shield, with what is called the umbo, a sharp protuberance, in the middle, with which they could as effectually annoy their enemies as defend themselves. Many of the old Highland targets were made with a projecting dagger in the center. Taking the proportions of things unknown to those known, the armor of Goliath is supposed to have weighed not less than two hundred and seventy-two pounds thirteen ounces! Plutarch informs us that the ordinary weight of a soldier's panoply, or complete armor, was one talent, or sixty pounds; and that one Alcimus, in the army of Demetrius, was considered as a prodigy, because his panoply weighed two talents, or one hundred and twenty pounds.

And the staff of his spear was like a weaver's beam,.... The wooden part of it, held in the hand; this for thickness was like the beam in the weaver's loom, about which the warp, or else the web, is rolled; and it is conjectured that, in proportion to the stature of Goliath, his spear must be twenty six feet long, since Hector's in Homer (m) was eleven cubits, or sixteen feet and a half:

and his spear's head weighed six hundred shekels of iron; the iron part of the spear, the point of it, which has its name in Hebrew from a flame of fire, because when brandished it looks shining and flaming; and being the weight of six hundred shekels, amounted to eighteen pounds and three quarters of avoirdupois weight, and the whole spear is supposed to weigh thirty seven pounds and a half; and the whole of this man's armour is thought to weigh two hundred and seventy two pounds, thirteen ounces (n); which was a prodigious weight for a man to carry, and go into battle with; and one may well wonder how he could be able with such a weight about him to move and lay about in an engagement; though this is nothing in comparison of the weight some men have carried. Pliny (o) tells us that he saw one Athanatus come into the theatre clothed with a leaden breastplate of five hundred pounds weight, and shod with buskins of the same weight:

and one bearing a shield went before him; which when engaged in battle he held in his own hand, and his sword in the other; the former was reckoned at thirty pounds, and the latter at four pounds, one ounce; though one would think he had no occasion for a shield, being so well covered with armour all over; so that the carrying of it before him might be only a matter of form and state. His spear is the only piece of armour that was of iron, all the rest were of brass; and Hesiod (p), writing of the brazen age, says, their arms and their houses were all of brass, for then there was no iron; and so Lucretius (q) affirms that the use of brass was before iron; but both are mentioned together; see Gill on Gen 4:22, hence Mars is called (r).

staff of his spear--rather under five feet long, and capable of being used as a javelin (Sa1 19:10). It had an iron head.

one bearing a shield--In consequence of their great size and weight, the Oriental warrior had a trusty and skilful friend, whose office it was to bear the large shield behind which he avoided the missile weapons of the enemy. He was covered, cap-a-pie, with defensive armor, while he had only two offensive weapons--a sword by his side and a spear in his hand.
