On the Life of the Wise Man made perfect by Instruction or, on the Unwritten Law, that is to say, on Abraham (141-145)

And a most evident proof of this is to be found in what is seen to this day: for the smoke which is still emitted, and the sulphur which men dig up there, are a proof of the calamity which befell that country; while a most conspicuous proof of the ancient fertility of the land is left in one city, and in the land around it. For the city is very populous, and the land is fertile in grass and in corn, and in every kind of fruit, as a constant evidence of the punishment which was inflicted by the divine will on the rest of the country.

But I have not gone through all these particulars for the sake of showing the magnitude of that vast and novel calamity, but because I desired to prove that of the three beings who appeared to the wise Abraham in the guise of men, the scriptures only represent two as having come to the country which was subsequently destroyed for the purpose of destroying its inhabitants, since the third did not think fit to come for that purpose.

Inasmuch as he, according to my conception, was the true and living God, who thought it fitting that he being present should bestow good gifts by his own power, but that he should effect the opposite objects by the agency and service of his subordinate powers, so that he might be looked upon as the cause of good only, and of no evil whatever antecedently.

And kings too appear to me to imitate the divine nature in this particular, and to act in the same way, giving their favours in person, but inflicting their chastisements by the agency of others.

But since, of the two powers of God, one is a beneficent power and the other a chastising one, each of them, as is natural, is manifested to the country of the people of Sodom. Because of the five finest cities in it four were about to be destroyed by fire, and one was destined to be left unhurt and safe from every evil. For it was necessary that the calamities should be inflicted by the chastising power, and that the one which was to be saved should be saved by the beneficent power.
