Type: supporting argument (off-timeline) · Assessment: weak — the harmonization saves the letter of "forty-two" only by reading the plain "son of forty-two years" idiom as a dynastic total the text never signposts, and it must still explain away the unanimous versional witness to the low-twenties figure · advanced by Matthew Poole, Jamieson–Fausset–Brown, and older Jewish harmonizers.

"Omri, who reigned six years… Ahab his son reigned twenty-two years… Ahaziah his son two years… Joram his son twelve years; all which, put together, make up exactly these forty-two years."
— Matthew Poole, Annotations, on 2 Chronicles 22:2, link. The interpretation: the "forty-two" is not Ahaziah's personal age but the age of the royal house from which his mother Athaliah came — the Omride dynasty — whose reigns, summed, reach forty-two years by his accession. On this reading 2 Kings 8:26 gives Ahaziah's own age (twenty-two) and 2 Chronicles 22:2 the dynasty's age, so both texts stand as written and neither is corrupt.1
Matthew Poole (1685) presses it first, though he also allows the copyist-error option; Jamieson–Fausset–Brown carry the same dynasty-reckoning ("the forty-second year of the kingdom of his mother's family"); and it echoes older Jewish harmonizations that dated the figure "from the founding" of the Omride house. A related variant, weaker still, takes the "forty-two" to be the age not of the dynasty but of Ahaziah's mother Athaliah.2 All of these are attempts to keep the received Hebrew as written rather than emend it.
It respects the received text. The harmonization's real appeal is that it emends nothing: the Masoretic "forty-two" stands, and the difficulty is dissolved by re-describing what is counted. For a reader committed to the integrity of the transmitted Hebrew, that is a genuine attraction.3
The arithmetic can be made to work. Omri's six years, Ahab's twenty-two, Ahaziah of Israel's two, and Joram's twelve do add to forty-two, and Athaliah — Ahaziah of Judah's mother — belonged to that house, so the dynasty is at least the right family to count. The sum is not invented from nothing.4
The Hebrew idiom is against it. 2 Chronicles 22:2 says Ahaziah "was a son of forty-two years" (ben-arbāʿîm ûšəttayim šānâ) — the identical construction 2 Kings 8:26 uses for his personal age ("a son of twenty-two years") and the standard biblical way of stating how old a person is. To make the same idiom mean "the dynasty was forty-two years old" in one verse and "the man was twenty-two years old" in its parallel is to read into the grammar a sense it does not bear.5
Nothing in the text signposts a dynastic total. The verse names Ahaziah, gives his one-year reign, and names his mother; it says nothing of Omri, of a founding date, or of counting a dynasty. The forty-two-year sum has to be assembled from four other reigns scattered across Kings and then read back into a verse that mentions none of them. That is reconstruction after the fact to reach a target number, not exegesis of what the verse says.6
It leaves the versions unexplained. Even granting the sum, the reading still faces the fact that no ancient version carries "forty-two": the Septuagint reads "twenty," the Syriac and Arabic "twenty-two." If the "forty-two" were a deliberate dynastic reckoning rather than a slip, the translators who had "forty-two" before them would have had no reason to render it as a personal age of twenty. The unanimous versional witness to the low-twenties figure is exactly what the scribal-error reading predicts and what the dynasty-reckoning cannot accommodate.7
The same shape as the stables-vs.-stalls move. Like the "different things being counted" harmonization on Solomon's stalls, this reading preserves the letter of a text by splitting one plain statement into two different objects of counting. There, both verses were shown to be one notice; here, both verses use one idiom for one thing — a person's age — and the split is imposed to avoid an emendation the evidence otherwise compels.8
Weak. The dynasty-reckoning is genuinely advocated and its arithmetic can be made to total forty-two, so it is not baseless; but it does not hold on its best case. It reads the plain "son of forty-two years" idiom — the same construction used for Ahaziah's age in the parallel — as a dynastic total the verse nowhere signposts, assembles that total from reigns the verse never mentions, and cannot explain why every ancient version carries the low-twenties figure instead. It saves the letter of the Masoretic text only by keeping the very number the arithmetic, the parallel, and the versions all mark as corrupt. The stronger reading is that "forty-two" is a scribal error for "twenty-two," rated sound.

The harmonization's stated aim is to keep the Masoretic reading rather than emend it; see Poole and JFB (as in nn. 1–2). ↩
Omri (six years, 1 Kings 16:23), Ahab (twenty-two, 1 Kings 16:29), Ahaziah of Israel (two, 1 Kings 22:51), Joram (twelve, 2 Kings 3:1) sum to forty-two; Athaliah, Ahaziah of Judah's mother, belonged to the Omride house. ↩
2 Chronicles 22:2 and 2 Kings 8:26 use the same "son of N years" construction (Hebrew ben-… šānâ), the standard idiom for a person's age. ↩
The verse names neither Omri nor any dynastic founding; the forty-two-year total is drawn from the four reigns cited in n. 4, none of which 2 Chronicles 22:2 mentions. ↩
Ellicott and the Cambridge Bible on 2 Chronicles 22:2: the Septuagint reads "twenty," the Syriac and Arabic "twenty-two" — no version carries "forty-two." ↩
Compare the "stables-vs.-stalls" harmonization on Solomon's stalls, which likewise saves both numbers by splitting one notice into two objects of counting. ↩
