John Chrysostom

And this again is the peculiarity of harlots that they are his who gives the gold. Even if he is a slave or a gladiator, or any person whatever, yet if he offers their hire they receive him. But the free, even should they be nobler than all, they do not accept without the money.… For that shamelessness makes harlots, hear the prophet saying, "You were shameless toward all. You had a harlot's countenance." This may be said to the covetous also, "You were shameless toward all," not toward these or those, but "toward all."
