Meaning
(2) The bow was common to civil (Ge 21:20) and military life (Zec 9:10), and vies with the spear in importance and antiquity. It was usually made of tough, elastic, seasoned wood, and often mounted with bronze (see Ps 18:34 Revised Version (British and American); compare Job 20:24). but horn, too, was used for bows by the ancients, some with double curves being evidently modeled after the horns of oxen. The bow-string was commonly ox-gut and the arrows were of reed, or light wood tipped with flint, bronze, or iron.
(3) The battle bows, such as are mentioned in Zec 9:10, Zec 10:4, must have been of great size, since they required to be strung by pressing the foot on the lower end, while the upper end was bent down to receive the string into a notch; hence the expression "to tread (= string) the bow," and "bowtreaders," for archers (Jer 50:14, Jer 50:29 Hebrew). The arrows, "the sons of his quiver" (La 3:13 margin, the Revised Version (British and American) "shafts"), were ordinarily, of course, carried in the quiver, which was either placed on the back or slung on the left side, secured by a belt over the right shoulder (HDB). The day of gunpowder and firearms, of course, was not yet.
