Abraham lives in a time in which the righteous are sacrificed on altars for refusing to cooperate with the state religion. This is exactly the sort of circumstance in which the visionary men write pseudonymous history.
The righteous in question are identified as "virgins," which may mean priestesses, "daughters of Zion." This echoes the reforms of Josiah.
"Potiphar's Hill" is a curious name. It suggests a corrupted woman, a vengeful ruler, and a priestly innocent who flees leaving his clothing behind.
