68 Following these, holy Eusebius went forth out of his country, and from his own relatives, and preferred a foreign wandering to ease at home. For the faith also he preferred and chose the hardships of exile, in conjunction with Dionysius of holy memory, who esteemed a voluntary exile above an Emperor's friendship. And so these illustrious men, surrounded with arms, closed in by soldiers, when torn away from the larger Church, triumphed over the imperial power, because by earthly shame they purchased fortitude of soul, and kingly power; they from whom the band of soldiers and the din of arms could not tear away the faith subdued the raging of the brutal mind, which was unable to hurt the saints. For, as you read in Proverbs, “the king's wrath is as the wrath of a lion.”
