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.[1][2] R.K. Harrison states that, “Jabal Musa ... seems to have enjoyed special sanctity long before Christian times, culminating in its identification with Mt. Sinai."[3] In the second and third centuries BCE Nabataeans were making pilgrimages there, which is indicated in part by inscriptions discovered in the area.[49][full citation needed] 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.[50]
