If you’ll step out, he’ll step in. 

Isokrates, Aiginetikos 5-6
Thrasyllos, the father of the testator, had inherited nothing from his parents; but having become the guest-friend of Polemaenetos, the soothsayer, he became so intimate with him that Polemaenetos at his death left to him his books on divination and gave him a portion of the property which is now in question. Thrasyllos, with these books as his capital, practiced the art of divination. He became an itinerant soothsayer, lived in many cities, and was intimate with several women.
