Jehoahaz

Jehoahaz is introduced as Jehu's successor, the first of the four generations God promised would sit on the throne — his ascension fulfills the dynastic reward God gave Jehu despite his incomplete obedience.

Jehoahaz is introduced as the new king who follows his father Jehu's dynasty but not Jehu's limited reforms — he reigns seventeen years in the same sin that got Israel into trouble.

Jehoahaz is Josiah's son whom the people immediately anoint after their king's death — the succession happens quickly, but his reign will last only three months before Egypt deposes him.

Jehoahaz is mentioned here as the one son the raiders left behind — his survival is the only thread keeping David's dynasty alive after his father's enemies take everyone else.

Jehoahaz is the people's chosen successor to Josiah, installed by popular will — a choice that Egypt immediately overrules, exposing how little sovereignty Judah actually has.

Jehoahaz is identified here as the alternate name for Shallum, Josiah's son — clarifying the identity of the king who reigned briefly before being deported to Egypt, never to return.

Jehoahaz is the likely referent for the first lion cub — the king who roared briefly before Pharaoh Neco dragged him to Egypt in chains after only three months on the throne.

Jehoahaz is the alternate name for Shallum, the deposed king being carried off to Egypt — God uses both names here to make clear exactly who this permanent exile sentence falls on.
