ABSTRACT
Hear, you princes who oppose your elder brethren and stir up war and incite the pagans against your brethren – lest God should reprove you at the Last Judgement – how saints Boris and Gleb endured from their brother not only the taking away of their domains but also the taking away of their lives. Yet you cannot endure even one word from your brother, and for the merest slight you stir up mortal enmity and receive aid from the pagans against your brethren. 1
