Have you not heard, "The saints shall rejoice in glory; and shall exult on their beds. The high praises of God shall be in their throat, and two-deged swords in their hands; to execute vengence on the nations and punishment among the peoples; to bind their kings with fetters and their nobles with manacles of iron; to execute on them the judgement written: This honor have all his saints." Psalm 149.
