The earliest references to Jabal Musa as Mount Sinai or Mount Sinai being located in the present day Sinai Peninsula are inconclusive. There is evidence that prior to 100 CE, well before the Christian monastic period, Jewish sages equated Jabal Musa with Mount Sinai. Graham Davies of Cambridge University argues that early Jewish pilgrimages identified Jabal Musa as Mount Sinai and this identification was later adopted by the Christian pilgrims. R. K. Harrison states that, “Jabal Musa . . . seems to have enjoyed special sanctity long before Christian times, culminating in its identification with Mt. Sinai." In the second and third centuries BCE Nabataeans were making pilgrimages there, which is indicated in part by inscriptions discovered in the area. In the 6th century, Saint Catherine's Monastery was constructed at the base of this mountain at a site which is claimed to be the site of the biblical burning bush.
