Wishing to learn the reason for his defeat, Elesbaan, with prompting from above, turned to a certain hermit. He revealed to the emperor that he had proceeded unrighteously in deciding to take revenge against Dunaan, since the Lord had said, “Vengeance is Mine, I will repay!” (Heb 10:30).
The hermit counseled Saint Elesbaan make a vow to devote his final days of life to God, to escape the wrath of God for his self-willed revenge, and then to defeat Dunaan. Saint Elesbaan made a vow to the Lord, and marching off with his army against the enemy, he defeated, captured and executed him. After the victory the saint resigned as emperor, secluded himself within a monastery and for fifteen years he dwelt in strict fasting and asceticism.
