Prayer of Manasses 1:8

8 Surely thou, O Lord, the God of the just, hast not appointed repentance for the just, for Abraham and Isaac and Jacob who have not sinned against thee; but thou hast appointed repentance for me a sinner:

Prayer of Manasses 1:8 In-Context

6 the mercy of thy promise is both immeasurable and inscrutable;
7 for thou art the Lord most high, compassionate, longsuffering, and most merciful, repenting of the evils of men. Thou, Lord, according to the abundance of thy goodness, hast proclaimed repentance and forgiveness to those that have sinned against thee, and in the multitude of thy kindnesses thou hast decreed for sinners repentance unto salvation.
8 Surely thou, O Lord, the God of the just, hast not appointed repentance for the just, for Abraham and Isaac and Jacob who have not sinned against thee; but thou hast appointed repentance for me a sinner:
9 for I have sinned above the number of the sand of the sea. My transgressions are multiplied, O Lord, they are multiplied, and I am not worthy to look at or see the height of heaven, for the multitude of my iniquities,
10 being bowed down by many iron bonds, so that I cannot uplift my head, and there is no release for me, because I have provoked thy anger, and have done evil before thee, not doing thy will, nor keeping thy commandments, but setting up abominations and multiplying offences.
