Another duty of the shepherd of ancient Palestine was to guard his flock from depredators, whether man or beast. Therefore the shepherd was forced to carry arms; to act as a sentry during the night; and, in fact, to be a sort of irregular soldier. A fully-armed shepherd had with him his bow, his spear, and his sword, and not even a shepherd lad was without his sling and the great quarter-staff which is even now universally carried by the tribes along the Nile—a staff as thick as a man's wrist, and six or seven feet in length. He was skilled in the use of all these weapons, especially in that of the sling.
DAVID GATHERS STONES FROM THE BROOK TO CAST AT GOLIATH.
In these days, the sling is only considered as a mere toy, whereas, before the introduction of fire-arms, it was one of the most formidable weapons that could be wielded by light troops. Round and smooth stones weighing three or four ounces were the usual projectiles, and, by dint of constant practice from childhood, the slingers could aim with a marvellous precision. Of this fact we have a notable instance in David, who knew that the sling and the five stones in the hand of an active youth unencumbered by armour, and wearing merely the shepherd's simple tunic, were more than a match for all the ponderous weapons of the gigantic Philistine.
It has sometimes been the fashion to attribute the successful aim of David to a special miracle, whereas those who are acquainted with ancient weapons know well that no miracle was wrought, because none was needed; a good slinger at that time being as sure of his aim as a good rifleman of our days.
The sling was in constant requisition, being used both in directing the Sheep and in repelling enemies: a stone skilfully thrown in front of a straying Sheep being a well-understood signal that the animal had better retrace its steps if it did not want to feel the next stone on its back.
