This, therefore, is the wife who is a citizen; but the concubine is she who sees one only of all existing things at a time, even though it may be the most worthless of all. It is given, therefore, to the most excellent race to see the most excellent of things, namely, the really living God; for the name Israel, being interpreted, means "seeing God."
But to him who aims at the second prize, it is allowed to see that which is second best, namely, the heaven which is perceptible by the external senses, and the harmonious arrangement of the stars therein, and their truly musical and well-regulated motion. The third class are the sceptics, who do not apply themselves to the most excellent objects, either of the intellect or of the external senses, which exist in nature, because they are always occupying themselves with petty sophistries, and small cavils, and criticisms. These have for their companions the concubine Rumah, who sees something which is very minute, because they are unable to approach the investigation of better things, by means of which they might benefit their own life. For, as among physicians that which is called
 
theoretical medical skill, is a long way from doing any good to those that are sick—for diseases are cured by medicines, and by operations, and by regimen, and not by discussions or theories; so also in philosophy, there is a set of word-traffickers and word-eaters, who have neither the will nor the skill to heal a life which is full of infirmities, but who, from their very earliest infancy to the extremity of old age, are not ashamed to cavil, and quibble, and wrangle about figurative expressions, as if happiness consisted in an interminable and profitless minuteness of accuracy in the matter of nouns and verbs, and not in the improving and ameliorating the moral character, the true fountain of the persons’ disposition; and in expelling the vices, and driving them out of its boundaries, and establishing the virtues as settlers within them.
 Now the wicked also have a desire for concubines, that is, for vain opinions and doctrines; accordingly Moses tells us that Thimna, the concubine of Eliphah the son of Esau, bore Amalek to Eliphah. Genesis xxxvi. 12. Alas, for the eminent ignobleness of the descendant! And you will see this ignobleness the more clearly, if you abandon the idea that this expression is used about a man, and rather consider the soul, with a kind of anatomical dissection. The historian then calls the irrational and immoderate desires and impetuosity of the passions, Amalek; now the name Amalek, being interpreted, means "the people looking up." For as the power of fire consumes the materials which are offered to it, so in the same manner does passion, when boiling over lick up and destroy everything with which it meets.
