 | THOU ART WORTHY TO TAKE THE BOOK  AND TO OPEN THE SEALS THEREOF,  FOR THOU WAS  SLAIN AND HAST  REDEEMED US UNTO GOD,  BY THY BLOOD,  BY THY BLOOD,  BY THY BLOOD,  BY THY BLOOD.  OUT OF EVERY KINDRED AND TONGUE AND  PEOPLE AND NATION AND HATH MADE US  A KINGDOM AND PRIESTS UNTO OUR GOD;  AND WE SHALL REIGN ,IN 'THE EARTH.
