He took his staff in his hand, and chose him five smooth stones out of the brook, and put them in the shepherd's bag which he had, even in his wallet; and his sling was in his hand: and he drew near to the Philistine.
And his sling — The sling, both among the Greeks and Hebrews, has been a powerful offensive weapon. See what has been said on Judges 20:16. 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.
