Monastic Withdrawal at the Lavra of Saint Savva
Following the death of his wife, Jonah withdrew to the Lavra of Saint Savva the Sanctified, the great monastic foundation of the Judean desert. Both of his sons had already been tonsured there before him.
At the Lavra he is described as practicing reverence toward God through asceticism, fasting, prayer, and continual tears. The tradition relates that, adorned with virtue, he acquired the gift of healing, so that many came to him seeking cures. He remained at the monastery until his repose in old age.
