LXXV.  The man who has been polluted with his own sister, either on the father’s or the mother’s side, must not be allowed to enter the house of prayer, until he has given up his iniquitous and unlawful conduct.  And, after he has come to a sense of that fearful sin, let him weep for three years standing at the door of the house of prayer, and entreating the people as they go in to prayer that each and all will mercifully offer on his behalf their prayers with earnestness to the Lord.  After this let him be received for another period of three years to hearing alone, and while hearing the Scriptures and the instruction, let him be expelled and not be admitted to prayer.  Afterwards, if he has asked it with tears and has fallen before the Lord with contrition of heart and great humiliation, let kneeling be accorded to him during other three years.  Thus, when he shall have worthily shown the fruits of repentance, let him be received in the tenth year to the prayer of the faithful without oblation; and after standing with the faithful in prayer for two years, then, and not till then, let him be held worthy of the communion of the good thing.
