Charles Ellicott Commentary 2 Chronicles 22:11

"But Jehoshabeath, the daughter of the king, took Joash the son of Ahaziah, and stole him away from among the king`s sons that were slain, and put him and his nurse in the bedchamber. So Jehoshabeath, the daughter of king Jehoram, the wife of Jehoiada the priest (for she was the sister of Ahaziah), hid him from Athaliah, so that she slew him not." — 2 Chronicles 22:11 (ASV)

Jehoshabeath. — In Kings, it is “Jehosheba.” (Compare “Elisheba,”Exodus 6:23; and Ἐλισάβετ (Septuagint), Luke 1:7.)

The daughter of the king. — Kings adds “Joram,” and “sister of Ahaziah.”

That were slain. — That were to be put to death.

In a bedchamber. — Literally, in the chamber of beds, i.e., where the bedding was kept. (See Note on 2 Kings 11:2.)

The wife of Jehoiada the priest. — So Josephus. Thenius questions the fact on the supposed grounds:

1. That the high priest did not live in the Temple; but the passage he alleges (Nehemiah 3:20–21) does not prove this for Jehoiada.

2. That the chronicler contradicts himself in asserting that the priest’s wife also lived within the sacred precinct; but again his reference (2 Chronicles 8:11) is irrelevant.

Ewald calls the statement in question “genuinely historical;” and there is not the smallest reason to doubt it.
