Celsus next, for form's sake, and with great want of precision, speaks of “the dreams of the chief butler and chief baker, and of Pharaoh, and of the explanation of them, in consequence of which Joseph was taken out of prison in order to be entrusted by Pharaoh with the second place in Egypt.” What absurdity, then, did the history contain, looked at even in itself, that it should be adduced as matter of accusation by this Celsus, who gave the title of True Discourse to a treatise not containing doctrines, but full of charges against Jews and Christians?
He adds: “He who had been sold behaved kindly to his brethren (who had sold him), when they were suffering from hunger, and had been sent with their asses to purchase (provisions);” although he has not related these occurrences (in his treatise). But he does mention the circumstance of Joseph making himself known to his brethren, although I know not with what view, or what absurdity he can point out in such an occurrence; since it is impossible for Momus himself, we might say, to find any reasonable fault with events which, apart from their figurative meaning, present so much that is attractive.
He relates, further, that “Joseph, who had been sold as a slave, was restored to liberty, and went up with a solemn procession to his father's funeral,” and thinks that the narrative furnishes matter of accusation against us, as he makes the following remark: “By whom (Joseph, namely) the illustrious and divine nation of the Jews, after growing up in Egypt to be a multitude of people, was commanded to sojourn somewhere beyond the limits of the kingdom, and to pasture their flocks in districts of no repute.”
Now the words, “that they were commanded to pasture their flocks in districts of no repute,” are an addition, proceeding from his own feelings of hatred; for he has not shown that Goshen, the district of Egypt, is a place of no repute. The exodus of the people from Egypt he calls a flight, not at all remembering what is written in the book of Exodus regarding the departure of the Hebrews from the land of Egypt. We have enumerated these instances to show that what, literally considered, might appear to furnish ground of accusation, Celsus has not succeeded in proving to be either objectionable or foolish, having utterly failed to establish the evil character, as he regards it, of our Scriptures.
