Psalm 79:10-13

New International Version - UK

Before our eyes, make known among the nations
    that you avenge the outpoured blood of your servants.
¹¹ May the groans of the prisoners come before you;
    with your strong arm preserve those condemned to die.
¹² Pay back into the laps of our neighbours seven times
    the contempt they have hurled at you, Lord.
¹³ Then we your people, the sheep of your pasture,
    will praise you for ever;
from generation to generation
    we will proclaim your praise.
