 Aspebetus was afterwards ordained priest and became bishop over his tribe, in which capacity he attended the Council of Ephesus in 431.When the report of this miracle had made the name of Euthymius famous throughout Palestine, and large crowds came to visit him in his solitude, he retreated with his disciple Domitian to the wilderness of Ruba, near the Dead Sea, living for some time on a remote mountain called Marda by the Byzantines - no other than the ancient Masada of Roman-era fame.When large crowds followed him to this place also, he decided to return to the neighbourhood of the monastery of Theoctistus, where he took up his abode in a cavern.
