XXXVI. (192) And we must here begin with the promise. There are four places where the oracles are given by way of question and answer, being contained in the exposition of the law, and having a mixed character. For, first, the prophet feels inspiration and asks questions, and then the father prophesies to him, giving him a share of his discourse and replies. And the first case where this occurs is one which would have irritated, not only Moses, who was the most holy and pious man that ever lived, but even any one who had only had a slight taste of piety. (193) A certain man, illegitimately born of two unequal parents, namely, an Egyptian father and a Jewish mother, and who disregarded the national and hereditary customs which he had learnt from her, as it is reported, inclined to the Egyptian impiety, being seized with admiration for the ungodly practices of the men of that nation; (194) for the Egyptians, almost alone of all men, set up the earth as a rival of the heaven considering the former as entitled to honours equal with those of the gods, and giving the latter no especial honour, just as if it were proper to pay respect to the extremities of a country rather than to the king's palace. For in the world the heaven is the most holy temple, and the further extremity is the earth; though this too is in itself worthy of being regarded with honour; but if it is brought into comparison with the air, is as far inferior to it as light is to darkness, or night to day, or corruption to immortality, or a mortal to God. (195) For, since that country is not irrigated by rain as all other lands are, but by the inundations of the river which is accustomed every year to overflow its banks; the Egyptians, in their impious reason, make a god of the Nile, as if it were a copy and a rival of heaven, and use pompous language about the virtue of their country.
