XXX. (100) And Jacob's brother, he says, was Jubal, [Ge 4:21.] and the interpretation of this latter name is "inclining," being symbolically speech according to utterance; for this is naturally the brother of intellect; and it is with extraordinary propriety that he called the conversation of that intellect which changes affairs, "inclining," for it agrees after a fashion and harmonizes with both, as the equivalent weight does in a scale, or as a vessel which is tossed by the sea inclines first to one side and then to the other, from the violence of the waves; for the foolish man has not learnt how to say anything firm or stable. (101) But Moses does not think it right to incline either to the right or to the left, or in short to any part of the earthly Edom; but rather to proceed along the middle way, which he with great propriety calls the royal road, [Nu 20:17.] for since God is the first and only God of the universe, so also the road to him, as being the king's road, is very properly denominated royal; and this royal road you must consider to be philosophy, not that philosophy which the existing sophistical crowd of men pursues (for they, studying the art of words in opposition to truth, have called crafty wickedness, wisdom, assigning a divine name to wicked action), but that which the ancient company of those men who practised virtue studied, rejecting the persuasive juggleries of pleasure, and adopting a virtuous and austere study of the honourable--(102) this royal road, which we have stated to be true and genuine philosophy, the law calls the word and reason of God; for it is written, "Thou shalt not turn aside from the word which I command thee this day, to the right hand nor to the left," So that it is shown most manifestly that the word of God is identical with the royal road, since Moses' words are not to depart either from the royal road, or from this word, as if the two were synonymous, but to proceed with an upright mind along the middle and level road, which leads one aright.
