We are now coming near this famous combat, and have in these verses the preparations and remonstrances made on both sides.

I.The preparations made on both sides for the encounter. The Philistine was already fixed, as he had been daily for the last forty days. Well might he go with his armour, for he had sufficiently proved it. Only we are told (Sa1 17:41) that he came on and drew near, a signal, it is likely, being given that his challenge was accepted, and, as if he distrusted his helmet and coat of mail, a man went before him, carrying his shield, for his own hands were full with his sword and spear, Sa1 17:45. But what arms and ammunition is David furnished with? Truly none but what he brought with him as a shepherd; no breastplate, nor corselet, but his plain shepherd's coat; no spear, but his staff; no sword nor bow, but his sling; no quiver, but his scrip; nor any arrows, but, instead of them, five smooth stones picked up out of the brook, Sa1 17:40. By this it appeared that his confidence was purely in the power of God, and not in any sufficiency of his own, and that now at length he who put it into his heart to fight the Philistine put it into his head with what weapons to do it.

II.The conference which precedes the encounter, in which observe,

1.How very proud Goliath was, (1.) With what scorn he looked upon his adversary, Sa1 17:42. He looked about, expecting to meet some tall strong man, but, when he saw what a mean figure he made with whom he was to engage, he disdained him, thought it below him to enter the lists with him, fearing that the contemptibleness of the champion he contended with would lessen the glory of his victory. He took notice of his person, that he was but a youth, not come to his strength, ruddy and of a fair countenance, fitter to accompany the virgins of Israel in their dances (if mixed dancing was then in use) than to lead on the men of Israel in their battles. He took notice of his array with great indignation (Sa1 17:43): "Am I a dog, that thou comest to me with staves? Dost thou think to beat me as easily as thou dost thy shepherd's dog?" (2.) With what confidence he presumed upon his success. He cursed David by his gods, imprecating the impotent vengeance of his idols against him, thinking these fire-balls thrown about him would secure his success: and therefore, in confidence of that, he darts his grimaces, as if threatening words would kill (Sa1 17:44): "Come to me, and I will give thy flesh to the fowls of the air, it will be a tender and delicate feast for them." Thus the security and presumption of fools destroy them.

2.How very pious David was. His speech savours nothing of ostentation, but God is all in all in it, Sa1 17:45-47. (1.) He derives his authority from God: "I come to thee by warrant and commission from heaven, in the name of the Lord, who has called me to and anointed me for this undertaking, who, by his universal providence, is the Lord of hosts, of all hosts, and therefore has power to do what he pleases, and, by the special grace of his covenant, is the God of the armies of Israel, and therefore has engaged and will employ his power for their protection, and against thee who hast impiously defied them." The name of God David relied on, as Goliath did on his sword and spear. See Psa 20:7; Psa 118:10, Psa 118:11. (2.) He depends for success upon God, Sa1 17:46. David speaks with as much assurance as Goliath had done, but upon better ground; it is his faith that says, "This day will the Lord deliver thee into my hand, and not only thy carcase, but the carcases of the host of the Philistines, shall be given to the birds and beasts of prey." (3.) He devotes the praise and glory of all to God. He did not, like Goliath, seek his own honour, but the honour of God, not doubting but by the success of this action, [1.] All the world should be made to know that there is a God, and that the God of Israel is the one only living and true God, and all other pretended deities are vanity and a lie. [2.] All Israel (whom he calls not this army, but this assembly, or church, because they were now religiously attending the goings of their God and King, as they used to do in the sanctuary) shall know that the Lord saveth not with sword and spear (Sa1 17:47), but can, when he pleases, save without either and against both, Psa 46:9. David addresses himself to this combat rather as a priest that was going to offer a sacrifice to the justice of God than as a soldier that was going to engage an enemy of his country.

He took his staff - What we would call his crook.

Five smooth stones -

1.Had they been rough or angular, they would not have passed easily through the air, and their asperities would, in the course of their passage, have given them a false direction.

2.Had they not been smooth, they could not have been readily despatched from the sling.

A shepherd's bag - That in which he generally carried his provisions while keeping the sheep in the open country.

And his sling - The sling, both among the Greeks and Hebrews, has been a powerful offensive weapon. See what has been said on Jdg 20:16 (note). It is composed of two strings and a leathern strap; the strap is in the middle, and is the place where the stone or bullet lies. The string on the right end of the strap is firmly fastened to the hand; that on the left is held between the thumb and middle joint of the fore finger. It is then whirled two or three times round the head; and when discharged, the finger and thumb let go their hold of the left end string. The velocity and force of the sling are in proportion to the distance of the strap, where the bullet lies, from the shoulder joint. Hence the ancient Baleares, or inhabitants of Majorca and Minorca, are said to have had three slings of different lengths, the longest they used when the enemy was at the greatest distance; the middle one, on their nearer approach; and the shortest, when they came into the ordinary fighting distance in the field. The shortest is the most certain, though not the most powerful. The Balearians are said to have had one of their slings constantly bound about their head, to have used the second as a girdle, and to have carried the third always in their hand. See Diod. Sic. lib. v., c. 18, p. 286, edit. Bipont.

In the use of the sling it requires much practice to hit the mark; but when once this dexterity is acquired, the sling is nearly as fatal as the musket or bow; see on Sa1 17:49 (note). David was evidently an expert marksman; and his sling gave him greatly the advantage over Goliath; an advantage of which the giant does not seem to have been aware. He could hit him within any speaking distance, if he missed once, he had as many chances as he had stones; and after all, being unencumbered with armor, young, and athletic, he could have saved his life by flight. Against him the Philistine could do but little, except in close fight; it is true he appears to have had a javelin or missile spear, (see on Sa1 17:6 (note)), but David took care to prevent the use of all such weapons, by giving him the first blow.

And he took his staff in his hand,.... His shepherd's staff, which he used in keeping his father's sheep, and chose rather to appear in the habit of a shepherd than of a soldier:

and chose him five smooth stones out of the brook; which ran in the valley, which became smooth by lying in the water running over them; and which being smooth were fitter for his purpose, being the more easily cast out of the sling; though De Dieu is of opinion that these were parts or pieces of stones, cleft ones, which were rough and rugged, and which would more easily and firmly be fixed in the forehead of the Philistine:

and put them in a shepherd's bag which he had, even in a scrip; in which he had been wont to put things he needed for the good of the flock, and was such as travellers put their food in; and this might also be the use of it with shepherds; but, according to the Ethiopic interpreters (k), it was that piece of the leather in the midst of the sling, in which the slingers used to put the stones, that they might stick the more firmly:

and his sling was in his hand; which he intended to use in slinging the stone or stones he had in his scrip; and which was an exercise he had been accustomed to in all likelihood, and for which the Benjaminites his neighbours, of the next tribe, were very famous:

and he drew near to the Philistine; marched towards him, thereby signifying that he accepted his challenge, and would enter the list with him.

brook--wady.

bag--or scrip for containing his daily food.

sling--The sling consisted of a double rope with a thong, probably of leather, to receive the stone. The slinger held a second stone in his left hand. David chose five stones, as a reserve, in case the first should fail. Shepherds in the East carry a sling and stones still, for the purpose of driving away, or killing, the enemies that prowl about the flock.
