"The same standards apply to heathen evidence as to biblica. Is it based on a primary source? Is it biased, ambiguous or simply wrong? Relevant evidence is extremely scarce; what, if anything, does silence imply? In the early parts of the Bible's story, biblical persons have yet to be identified correctly in any external sources. There have been many attempts, and some confident claims, but as yet there is no good reason to identify Moses or Joseph with any known person or period in ancient Egyptian records." Robin Lane Fox, The Unauthorized Version, (New York: Vintage, 1993), p. 252.
