23. In the case of figurative signs, again, if ignorance of any of them should chance to bring the reader to a standstill, their meaning is to be traced partly by the knowledge of languages, partly by the knowledge of things. The pool of Siloam, for example, where the man whose eyes our Lord had anointed with clay made out of spittle was commanded to wash, has a figurative significance, and undoubtedly conveys a secret sense; but yet if the evangelist had not interpreted that name, a meaning so important would lie unnoticed. And we cannot doubt that, in the same way, many Hebrew names which have not been interpreted by the writers of those books, would, if any one could interpret them, be of great value and service in solving the enigmas of Scripture. And a number of men skilled in that language have conferred no small benefit on posterity by explaining all these words without reference to their place in Scripture, and telling us what Adam means, what Eve, what Abraham, what Moses, and also the names of places, what Jerusalem signifies, or Sion, or Sinai, or Lebanon, or Jordan, and whatever other names in that language we are not acquainted with. And when these names have been investigated and explained, many figurative expressions in Scripture become clear.
