But that what is seen is in reality a threefold appearance of one subject is plain, not only from the contemplation of the allegory, but also from that of the express words in which the allegory is couched. For when the wise man entreats those persons who are in the guise of three travellers to come and lodge in his house, he speaks to them not as three persons, but as one, and says, "My lord, if I have found favour with thee, do not thou pass by thy servant." Genesis xviii. 3. For the expressions, "my lord," and "with thee," and "do not thou pass by," and others of the same kind, are all such as are naturally addressed to a single individual, but not to many.

 "The greatest cause of all iniquity 
 Is found in overmuch prosperity." 
 As men, being unable to bear discreetly a satiety of these things, get restive like cattle, and become stiff-necked, and discard the laws of nature, pursuing a great and intemperate indulgence of gluttony, and drinking, and unlawful connections; for not only did they go mad after women, and defile the marriage bed of others, but also those who were men lusted after one another, doing unseemly things, and not regarding or respecting their common nature, and though eager for children, they were convicted by having only an abortive offspring; but the conviction produced no advantage, since they were overcome by violent desire;
