These are they who neither knew Joseph—the diversified pride of life—but who, having their sins revealed, have not received any trace, or shade, or image of goodness and excellence. For, says Moses, "Another king arose over the Egyptians who knew not Joseph," Exodus i. 8. the latest and most modern good perceptible by the outward senses, who utterly destroyed not only the perfections but even all improvements, and all the energy which can be exerted by the sight, and all the teaching which can be implanted by means of the hearing, saying, "Come, curse me Jacob; and come, defy Israel for me;" Numbers xxiii. 7 an expression which is equivalent to, Destroy both these things, the sight and the hearing of the soul, that it may neither see nor hear any true and genuine good thing; for Israel is the emblem of seeing and Jacob of hearing. Accordingly the mind of such persons rejects the whole nature of good, being in some degree shaken; and, on the other hand, the mind of good persons, setting up a claim to the unmingled and unalloyed ideas of good things, shakes off and discards all that is evil.
 Consider, therefore, what the practiser of virtue says: "Take up the foreign gods that are among you from out of the midst of you, and purify yourselves, and change your garments, and rise up and let us go to Bethel;" Genesis XXXV. 2. in order that, even if Laban should demand a power of examining, the images might not be found in his whole house, but only such things as have a real subsistence and essence, being fixed like pillars in the mind of the wise man, which the self-taught offspring Isaac has received as his inheritance; for he alone receives his father’s substance as his inheritance." Genesis xxv. 5. 
 And take notice that Moses does not say that they came unto a plain in which they remain, but that they "found" one, having searched around in every direction, and having considered what might be the most suitable region for folly; for in reality every foolish man does not take from another for himself, but he seeks for and finds evils, not being content only with those which wicked nature proceeds towards of its own accord, but also adding thereto such perfect skill in evil as arises from constant practise in contriving wrong.
