Steven James Schweitzer, «The High Priest in Chronicles: An Anomaly in a Detailed Description of the Temple Cult», Vol. 84 (2003) 388-402
The high and chief priests mentioned in both the genealogy of 1Chr 6,1-15 and the narrative of Chronicles (Zadok and Hilkiah) are compared with priests mentioned only in the narrative (the Azariah under Uzziah, the Azariah under Hezekiah, and Jehoiada); the Amariah under Jehoshaphat, possibly Amariah II in 1 Chr 6,11, is treated separately. This article concludes: Chronicles has not enhanced the Zadokite high priests; the three priests not mentioned in the genealogy are presented with increased cultic roles which delineate some of their duties; leading priests in Chronicles operate within the cultic sphere while their precise ceremonial role is unclear.
the house of God" (2 Chr 31,13). Azariah has administrative responsibilities in the cult. However, he has no authority beyond this role and is responsible to the Davidic king.
c) Jehoiada
The depiction of Jehoiada, apparently a non-Zadokite, presents the largest amount of data concerning the office of leading priest (2 Chr 22–24). His portrayal in Chronicles is consistent in many ways with that in 2 Kgs 11–1225. There are, however, several instances of an increased role and power being attributed to Jehoiada by the Chronicler which are not stated explicitly or clearly in his source26. Jehoiada has married into the Davidic line as his wife is the daughter of King Jehoram. This additional information has been seen by scholars as an attempt by the Chronicler to protect the purity of the temple since this female Davidide lives in the house of God for six years. However, this explanation does not account for Joash’s presence, which would also be a problem and which Chronicles does not address. In addition, such a marriage would seem to violate the purity regulations for the "priest exalted above his brothers" in Lev 21,10-15 which command this priest to marry only a virgin of his own kin. Jehoiada is obviously in violation of this command (if it even applies to him)27.
