Son of Yoram and Atalyah; reigned only one year in Yerushalayim, at age 22 (2 Kings 8:26) — 2 Chronicles 22:2 gives his age as 42, almost certainly a scribal error since that would make him older than his own father, a well-known textual difficulty
2 Kings 8:27 — 'he walked in the way of the house of Achav... for he was the son-in-law of the house of Achav' (i.e. through his mother Atalyah)
Allied with his uncle Yehoram/Yoram, king of Israel (Achav's son), against Aram at Ramot-Gilead
Visited the wounded Yehoram of Israel at Yizre'el, and was caught up in Yehu's purge of the house of Achav — Yehu's men struck him down as he fled, and he died at Megiddo (2 Kings 9:27–28)
His death triggered his mother Atalyah's seizure of the throne and massacre of the royal line (2 Kings 11:1) — see the note on 'atalyah'
“Walked in the way of the house of Achav, for he was its son-in-law — one of three kings Matthew's genealogy compresses past”
Traditional note: FLAGGED: Matthew 1:8 reads '...and Joram begat Uzziah...', skipping Achazyahu, Yoash, and Amatzyahu entirely — three full generations omitted in a single step. This is part of Matthew's deliberate compression of the genealogy into three sets of fourteen generations (Matthew 1:17), and is widely recognized by scholars as intentional telescoping rather than an error or a claim that these kings did not exist; 1–2 Kings and 2 Chronicles record all three in detail. This dataset includes Achazyahu, Yoash, and Amatzyahu as full entries, with father/children fields reflecting the historical succession from Kings/Chronicles, because the project's stated goal is that 'the messianic line David→Yeshua must be complete/consistent' — the Matthew-genealogy compression is documented here and on each of the three entries' notes, rather than adopted as this dataset's father/children chain (which would otherwise skip three real generations and make 'genealogy_position' inaccurate as a depth-tracker).
