Ḥorvat Gerarit; Kh. Umm Jerar - SILVANUS (?)

VI, 32, 8

I think that Silvanus, a native of Palestine, to whom, on account of his high virtue, an angel was once seen to minister, practiced philosophy about the same time in Egypt. Then he lived at Mount Sinai, and afterwards founded at Gerari, in the wady, a very extensive and most noted cœnobium for many good men, over which the excellent Zacharias subsequently presided.

Mention of Silvanus and his life among the monks of Palestine, from an ecclesiastical history written AD 440-450.
