The Prayer of Manasseh (or Manasses) is a short work of 15 verses recording a penitential prayer attributed to King Manasseh of Judah. Most scholars believe that the Prayer of Manasseh was written in Greek in the 1st or 2nd century BC. Another work by the same title, written in Hebrew and containing distinctly different content, was found among the Dead Sea Scrolls.
1 O Lord Almighty, that are in Heaven, You God of our fathers, of Abraham, and Isaac, and Jacob, and of their righteous seed; 2 who have made the heavens and earth, with all the ornament thereof; 3 who have bound the sea by the word of Your command; who have shut up the deep, and sealed it by Your terrible and glorious Name; 4 whom all things fear, yes, tremble before Your power; 5 for the majesty of Your glory cannot be borne, and the anger of Your threatening toward sinners is importable: 6 Your merciful promise is unmeasurable and unsearchable; 7 for You are the Lord Most High, of great compassion, patient and abundant in mercy, and relenting of bringing evils on men. 8 You, O Lord, according to Your great goodness have promised conversion and forgiveness to those who have sinned against You: and of Your infinite mercies have appointed conversion to sinners, that they may be saved. You, therefore, O Lord, that are the God of the just, have not appointed conversion to the just, to Abraham, and Isaac, and Jacob, which have not sinned against You; but You have appointed conversion to me that am a sinner: 9 for I have sinned above the number of the sands of the sea. My transgressions are multiplied, O Lord: my transgressions are multiplied, and I am not worthy to behold and see the height of Heaven for the multitude of my iniquities. 10 I am bowed down with many iron bands, that I cannot lift up my head by reason of my sins, neither do I have any respite, for I have provoked Your wrath and done that which is evil before You: I did not do Your will, neither did I keep Your commands: I have set up abominations and have multiplied detestable things. 11 Now therefore, I bow the knee of my heart, imploring You of grace. 12 I have sinned, O Lord, I have sinned, and I acknowledge my iniquities: 13 but, I humbly implore You, forgive me, O Lord, forgive me, and do not destroy me with my iniquities. Do not be angry with me forever, by reserving evil for me; neither condemn me into the lower parts of the earth. For You, O Lord, are the God of those who convert; 14 and in me You will show all Your goodness, for You will save me, that am unworthy, according to Your great mercy. 15 And I will praise You forever all the days of my life, for all the army of Heaven sings Your praise, and Yours is the glory forever and ever. Amen.
