XLVII. (227) And it is worth while to consider why, after having explained the measures of the table and of the altar of incense, he has given no such description of the candlestick; may it not be, perhaps, for the reason that the elements and all the mortal things which are compounded of them, of which the table and the altar of incense are symbols, have been measured, inasmuch as they are terminated in heaven? For that which surrounds anything is invariably the measure of that which is surrounded; but the heaven, of which the candlestick is the symbol, is of infinite magnitude; (228) for it is indeed surrounded, but not, according to the account of Moses, by a vacuum, nor by any substance, nor by anything which is of equal magnitude with itself, nor by anything of unlimited size, in accordance with the marvellous fables which we touched upon when speaking of their building of the tower; but its boundary is God, and he also is its ruler and the director of its course. (229) As, therefore, the living God is incomprehensible, so also that which is bounded by him is not measured by any measures which come with the range of our intellect; and, perhaps, inasmuch as it is of circular form and skilfully fashioned into a perfect sphere, it has no participation in either length or breadth.
