Against him that bendeth— Let not him who bendeth the bow relax his hand; let him not put off his armour. Houbigant.
And against him that lifteth himself up in his brigandine— And let him not lift up himself in his brigandine. This is exactly parallel in sense to the preceding part of the verse, if the posture of him that stoops to bend the bow be considered. For in using the large and strong steel bows, which could not be bent by the force of the arms, they rested one end upon the ground, and pressing the other with the foot or knee, they drew back the arrow with their hands as far as ever they could, in order that it might fly with greater force. Hence the archer is called קשׁת דרךֶ dorec kesheth, one that treadeth the bow. And therefore when he is bid not to lift himself up in his coat of mail, it is the same as bidding him not to desist from shooting with his bow.
