because of the glittering:

If I whet my glittering sword, and mine hand take hold on judgment; I will render vengeance to mine enemies, and will reward them that hate me. It is drawn, and cometh out of the body; yea, the glittering sword cometh out of his gall: terrors are upon him. The quiver rattleth against him, the glittering spear and the shield. And thou, son of man, prophesy and say, Thus saith the Lord God concerning the Ammonites, and concerning their reproach; even say thou, The sword, the sword is drawn: for the slaughter it is furbished, to consume because of the glittering: The horseman lifteth up both the bright sword and the glittering spear: and there is a multitude of slain, and a great number of carcases; and there is none end of their corpses; they stumble upon their corpses: The sun and moon stood still in their habitation: at the light of thine arrows they went, and at the shining of thy glittering spear.
