The strife is o'er the battle done now is the victor's triumph won now let the song of joy besung: Alleluia. On the third morn he rose again glorious in majesty to reign O let us swell the joyful strain Alleluia. Lord by the stripes which wounded thee from death's dread sting thy servants free that we may live and sing to thee: Alleluia.
