According to his biographer and disciple Dositheus, while he was young in years he was perfect in wisdom, and the boy differed from other children by his high spiritual aspirations, with never a contradiction in his words, knowledge and actions.

At the age of 10 he secretly left home for the Transfiguration Ugorniki Monastery, and asked the hegumen (abbot) to accept him to serve the brothers.

After the repeated offers of a local, Konstantin Ostrozhsky, the defender of Orthodoxy, he was transferred to the island monastery of the Exaltation of the Cross outside of Dubno that belonged to the duke's estates in the Rivne region.

It was translated into Russian and republished in 1881 under the title Pchela Pochayevskaya (The Bee of Pochayiv), edited by the professor of the Kiev Theological Academy, N. Petrov.

Many Orthodox Christians living in Poland at the time were deprived of their rights, and attempts were made to force them to convert to Catholicism.

For many days and weeks he would retreat into his locked cave, so narrow that entry is difficult, and so small that it was impossible to sit, stand or lie conveniently.

His disciple Dosyfey recounts that he saw supernatural light coming from the depths of the cave, shining for two hours onto the opposite side of the church.

During his time in office, the monastery had to fend off incessant attacks by Andrzej Firlej, Castellan of Belz, who sued the monks over his grandmother's bequest of extensive lands and a miracle-working icon of the Mother of God.

Every year, on 28 August a great number of Orthodox pilgrims come to Pochayev Lavra to honour Saint Job, venerate his relics, and ask for his intercession.

During the Zbarazh War of 1675, the cloister was besieged by the Turks, who reputedly fled upon seeing the apparition of the Theotokos (Mother of God) accompanied by angels and Job.

The cave church of St Job contains a famous gift from Countess Orlova - a silver reliquary with relics of the saint.
