for the mind is eaten out and destroyed by each separate one of the outward senses as by a moth, being shaken to pieces and lacerated; for the imaginations which enter it, not according to pleasure, make life itself mutilated and laborious. But On is said to be a hill, and it means, symbolically, the mind; for all reasonings are stored up in the mind: and the lawgiver himself is a witness of this, calling On, Heliopolis, the city of the sun. For as the sun, when he rises, shows visibly the things
 Genesis xi. 4. 
 There is a hiatus in the text here: Mangey translates it as if the deficiency were to be supplied by rov νοῦν , " the mind." 
 Exodus i. 11. 
 
which have been hidden by night, so also the mind, sending forth its own proper light, causes all bodies and all things to be seen visibly at a distance. On which account, a man would not be wrong who called our minds the sun of our composition; as the mind, if it does not rise and shed its own light in man, who may be looked upon as a small world, leaves a great darkness diffused over all existing things, and suffers nothing to be brought to light.
 This hill Jacob, the wrestler with God, in his agreements with Laban, calls a witness, showing in a most express manner, and in the form of a precept, that the mind is a witness to each individual of the determinations which he comes to in secret; and conscience, which is the most incorruptible and truth-telling witness of all, was built before these cities; for Moses says that the spies came to Chebron, and these three are Acheman, and Jesein, and Thalamein, of the sons of Enoch: and this he adds, "and Chebron was built seven years before Janis, in Egypt," Numbers xiii. 23. and these synonymous appellations are distinguished according to their species in a most natural manner.
Chebron, being interpreted, means compunction, and this is of two kinds; one with reference to the soul being joined to the body, the other with reference to its being adapted to virtue.
