Catena Aurea · Matthäusevangelium 10
Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves. But beware of men: for they will deliver you up to the councils, and they will scourge you in their synagogues; And ye shall be brought before governors and kings for my sake, for a testimony against them and the Gentiles.
(Hom. in Ev. xxxv. 2.) Either that they had persecuted to the death, or that they had seen and were not changed. For the death of the saints is to the good an aid, to the bad a testimony; that thus the wicked may perish without excuse in that from which the elect take example and live.
