Saint Jonah was the brother of Saint Barachisius.
The brothers Jonah and Barachisius were Christians who lived in the village of Yasa in Persia during the time of the emperor Sapor (310-331), a fierce persecutor of Christians.
Learning that Christians were being tortured in the city of Baravokh, they went there to the prison where Saints Zanithas, Lazarus, Maruthas, Narses, Elias, Marinus, Habib, Sivsithina and Sava were being held.
They encouraged them to adhere to the Christian Faith until the very end. The holy martyrs firmly confessed their faith in Christ and would not agree to the demands of the pagans. Therefore, they were subjected to fierce torments and death.
The bodies of the holy martyrs Jonah, Barachisius and the other martyrs were buried by a pious Christian named Habdisotes.
