Here, the prophet provides the picture of an arrow, indicating that the shaft of the arrow must be polished before its use. The shaft is one of an arrow’s most important components. If the shaft of the arrow is warped or misaligned in any way, the arrow will not hit its mark. A crooked shaft ultimately renders an arrow useless. The arrow’s sharp head is of little value if a malformed shaft causes it to miss its mark.
On the other hand, an arrow would also have little value if it reached its mark, but a dull head rendered it unable to stick. Both the arrow’s shaft and the head of the arrow are of equal importance. The shaft of the arrow speaks of the character of the armorbearer, while the head speaks of their function. Both the character and the function of a true armorbearer must go through a proper period of preparation.
