12. But inasmuch as some Scriptures have not the "corporeal," as we shall presently show, in such cases we must seek only the "soul" and the "spirit." For instance, this may explain why the six waterpots of stone said to be set after the Jews' manner of purifying, as we read in the Gospel according to John, contain two or three firkins apiece: the Word darkly hinting at those who were inwardly Jews, of whom the Apostle speaks ----that these, forsooth, are cleansed through the word of Scripture, that Word sometimes containing two firkins, that is, if we may so say, the "soul" and "spirit" of the Word: sometimes three; for some Scriptures have besides these two also the "corporeal" part with its power of edification. As for the number, the six waterpots may reasonably refer to those who are being purified in the world, which was made in six days, six being a perfect number.
