Prayer of Manasses 1:8

You, O Lord, according to your great goodness have promised repentance and forgiveness to those who have sinned against you. Of your infinite mercies, you have appointed repentance to sinners, that they may be saved. You therefore, O Lord, who are the God of the just, have not appointed repentance to the just, to Abraham, Isaac, and Jacob, which have not sinned against you, but you have appointed repentance to me, a sinner.
