The House of Imran were a Zadokite priesthood forced through the Torah literal literalism of the Temple system to side with Beth Shammai Zadokite priesthood longing for a sign from heaven to validate the stance of Beth Hillel and who rivaled the Sadduccee pseudo-Zadokite priesthood. Petrines believe the life and prophecies of Jesse ben Marym (whom they regard as a messiah) was the sign which nullified the legality of the 18 ordinances of the house of Shammai (Yerushalmi Berakhot, 1:7).
