In the days of Sapor, the Persian king, there lived a Christian named Dada, who was beloved by the king and appointed to govern one of the provinces. Upon learning of his Christian faith, the king entrusted the nobleman Andromelich to investigate this matter. Dada, making the sign of the cross, miraculously survives in the fire. His faith leads to the conversion of the royal prince Gavedday, who also begins to profess Christ. For this, Gavedday is subjected to cruel tortures, but he remains unharmed thanks to God's help.
Gargal, the judge, attempts to destroy the saint, but each time he fails, as the saint heals from his wounds. Gavedday and Gargal, who has become a Christian, suffer together for their faith. Kazdoya, the king's daughter, also turns to Christ and undergoes torture. Saint Gavedday, remaining steadfast, continues to pray and heal others in prison.
The king, learning of the miracles, orders Gavedday to be crucified, but he remains unharmed. Eventually, the holy martyr dies, and his relics are buried with honor by the Christians. Kazdoya, after baptism, dies, and their mother, witnessing the king's cruelty, mourns for her children.
The sufferings and death of the holy martyrs Dada, Gavedday, and Kazdoya occurred around the middle of the 4th century.
