Isaiah 30:32

And it shall happen to him from every side, [that] they from whom their hope of assistance was, in which he trusted, themselves shall war against him in turn with drums and with harp.

And in every place where the grounded staff shall pass, which the Lord shall lay upon him, it shall be with tabrets and harps: and in battles of shaking will he fight with it.

Every stroke of the rod of punishment, which Yahweh will lay on him, will be with the sound of tambourines and harps. He will fight with them in battles, brandishing weapons.
