The shepheras sling. It was a simple affair, being composed of two strings of sinew, rope, or leather, and a receptacle of leather to receive the stone. It was swung a time or two around the head and then was discharged by letting go one of the strings.
The shepherd, in addition to using his sling against wild animals or robbers, found it very handy in directing the sheep. A stone could be dropped close to a sheep that was lagging behind and startle it into coming along with the rest of the flock. Or if one would get away in another direction, then a stone would be slung so as to drop just beyond the straying sheep, and thus bring him back. It was the shepherd's sling that young David used in slaying the giant Goliath (I Samuel 17:40-49).
In her plea to David, Abigail was no doubt contrasting two items of his shepherd's equipment when she said, "The soul of my lord shall be bound in the bundle of life with the Lord thy God; and the souls of thine enemies, them shall he sling out, as out of the middle of a sling" (I Samuel 25:29). The "bundle of life" is understood as either "the pouch of life," or "the bag of life," and most probably refers to the shepherd's scrip. David's enemies were to be like the stones in his sling, being that which was to be thrown away; whereas David's soul would be like the provisions in his scrip, which were to be kept and guarded by the LORD himself.
