Prayer of Manasseh
Raymond E. Brown writes: "The piety is that of late Judaism, and the deuterocanonical prayer of Azariah (Dn 3:24-90) offers some interesting parallels. The Prayer of Manasseh was originally composed in Greek by a Jew in the 1st or 2nd cent. AD. It was promptly translated from Greek into Syriac, and thus our earliest extant form of the Prayer is in a 3rd-cent. Christian Syr work, the Didascalia. Although the prayer did not appear in early Vg mss., it is found in medieval mss. The Sixto-Clementine Vg printed it as a supplement (after Trent failed to list it as canonical). Protestants count it as one of 'the Apocrypha.'" (The Jerome Biblical Commentary, vol. 1, p. 541)
 for thy glorious splendor cannot be borne, and the wrath of thy threat to sinners is irresistible;
 yet immeasurable and unsearchable is thy promised mercy,
 for thou art the Lord Most High, of great compassion, long-suffering, and very merciful, and repentest over the evils of men. Thou, O Lord, according to thy great goodness hast promised repentance and forgiveness to those who have sinned against thee; and in the multitude of thy mercies thou hast appointed repentance for sinners, that they may be saved.
 Therefore thou, O Lord, God of the righteous, hast not appointed repentance for the righteous, for Abraham and Isaac and Jacob, who did not sin against thee, but thou hast appointed repentance for me, who am a sinner.
 For the sins I have committed are more in number than the sand of the sea; my transgressions are multiplied, O Lord, they are multiplied! I am unworthy to look up and see the height of heaven because of the multitude of my iniquities.
 I am weighted down with many an iron fetter, so that I am rejected because of my sins, and I have no relief; for I have provoked thy wrath and have done what is evil in thy sight, setting up abominations and multiplying offenses.
 And now I bend the knee of my heart, beseeching thee for thy kindness.
 I have sinned, O Lord, I have sinned, and I know my transgressions.
 I earnestly beseech thee, forgive me, O Lord, forgive me! Do not destroy me with my transgressions! Do not be angry with me for ever or lay up evil for me; do not condemn me to the depths of the earth. For thou, O Lord, art the God of those who repent,
 and in me thou wilt manifest thy goodness; for, unworthy as I am, thou wilt save me in thy great mercy,
