If any cleric has committed murder and killed his neighbour, let him do penance for ten years in exile. After these let him be restored to his native land, if he has performed his penance well on bread and water, being approved by the testimonial of the bishop or priest with whom he did penance and to whose care he was entrusted, on condition that he make satisfaction to the relatives of the slain, playing the part of a son, and saying, Whatever you wish I will do for you. But if he has not made satisfaction to his relatives, let him never be restored to his native land, but like Cain let him be a wanderer and fugitive upon the earth.
cf. Paen. Venniani 23
