The Martyrdom of Polycarp
Chapter 6: Polycarp is Betrayed by a Servant
And when those who sought him were near, he left for another dwelling, where his pursuers immediately followed him. And when they didn't find him, they seized two youths who were there. One of them, after being tortured, confessed. It was then impossible for him to remain hidden, as those who betrayed him were from his own household. The Irenarch, whose office is the same as that of the Cleronomus, named Herod, hurried to bring him to the stadium. This all happened so he could fulfill his special fate, becoming a partaker of Christ, and so those who betrayed him might face the same punishment as Judas himself.
