Targum do Rodzaju 18:24

Perhaps there are fifty innocent persons within the city, who pray before Thee,--ten for every city, of all the five cities of Sedom, Amorah, Admah, Zeboim, and Zoar. Wilt Thou in Thy displeasure destroy and not forgive the country, on account of the fifty innocent ones who are in it? Unholy would it be before Thee to do according to this word, to slay the innocent with the guilty, and to make the innocent to be as the guilty!
