God granted his petition, yet Abraham continued to plead, and he asked whether God would not be satisfied if there were but thirty righteous, ten in each of the three larger cities, and would pardon the two smaller ones, even though there were no righteous therein, whose merits would intercede for them. This, too, the Lord granted, and furthermore He promised not to destroy the cities if but twenty righteous were found therein; yes, God conceded that He would preserve the five cities for the sake of ten righteous therein.[164] More than this Abraham did not ask, for he knew that eight righteous ones, Noah and his wife, and his three sons and their wives, had not sufficed to avert the doom of the generation of the flood, and furthermore he hoped that Lot, his wife, and their four daughters, together with the husbands of their daughters, would make up the number ten. What he did not know was that even the righteous in these sin-laden cities, though better than the rest, were far from good.[165] Abraham did not cease to pray for the deliverance of the sinners even after the Shekinah had removed from him. But his supplications and his intercessions were in vain.[166] For fifty-two years God had warned the godless; He had made mountains to quake and tremble. But they hearkened not unto the voice of admonition. They persisted in their sins, and their well-merited punishment overtook them.[167] God forgives all sins, only not an immoral life. And as all these sinners led a life of debauchery, they were burnt with fire.[168] THE DESTRUCTION OF THE SINFUL CITIES The angels left Abraham at noon time, and they reached Sodom at the approach of evening. As a rule, angels proclaim their errand with the swiftness of lightning, but these were angels of mercy, and they hesitated to execute their work of destruction, ever hoping that the evil would be turned aside from Sodom.[169] With nightfall, the fate of Sodom was sealed irrevocably, and the angels arrived there.[170] Bred in the house of Abraham, Lot had learnt from him the beautiful custom of extending hospitality, and when he saw the angels before him in human form, thinking they were wayfarers, he bade them turn aside and tarry all night in his house. But as the entertainment of strangers was forbidden in Sodom on penalty of death, he dared invite them only under cover of the darkness of night,[171] and even then he had to use every manner of precaution, bidding the angels to follow him by devious ways. The angels, who had accepted Abraham's hospitality without delay, first refused to comply with Lot's request, for it is a rule of good breeding to show reluctance when an ordinary man invites one, but to accept the invitation of a great man at once. Lot, however, was insistent, and carried them into his house by main force.[172] At home he had to overcome the opposition of his wife, for she said, "If the inhabitants of Sodom hear of this, they will slay thee."
