Jesus and Ganid gave first aid to a lad named Rufus, who had been injured by a breakdown. His father, Simon, little dreamed that the man whose cross he subsequently bore by orders of a Roman soldier was the stranger who once befriended his son.  Simon was the father of Rufus and Alexander from Cyrene. Both sons became very effective teachers of the new gospel in Africa.
