1 Enoch 47
2In those days the holy ones who dwell above in the heavens Shall unite with one voice And supplicate and pray and praise, And give thanks and bless the name of the Lord of Spirits On behalf of the blood of the righteous which has been shed, And that the prayer of the righteous may not be in vain before the Lord of Spirits, That judgement may be done unto them, And that they may not have to suffer for ever.
4And the hearts of the holy were filled with joy; Because the number of the righteous had been offered , And the prayer of the righteous had been heard, And the blood of the righteous been required before the Lord of Spirits.
