While not technically a prayer, but a passage, from the Book of Enoch CHAP 99

1. In those days the angels shall descend into places of concealment, and gather together in one spot all who have assisted in crime.

2. In that day shall the Most High rise up to execute the great judgment upon all sinners, and to commit the guardianship of all the righteous and holy to the holy angels, that they may protect them as the apple of an eye, until every evil and every crime be annihilated.

3. Whether or no the righteous sleep securely, wise men shall then truly perceive.

4. And the sons of the earth shall understand every word of that book, knowing that their riches cannot save them in the ruin of their crimes.

5. Woe to you, ye sinners, when you shall be afflicted on account of the righteous in the day of the great trouble; shall be burnt in the fire; and be recompensed according to your deeds.

6. Woe to you, ye perverted in heart, who are watchful to obtain an accurate knowledge of evil, and to discover terrors. No one shall assist you.
