In 2 Kings 13:10, Jehoash began reign in Joash's 37th year; here Amaziah begins in Jehoash's 2nd year, synchronizing reigns.

2 Chronicles 25:1-4 gives the parallel account of Amaziah's accession with same details (age, mother, and justice).

1 Chronicles 3:12 lists Amaziah in David's genealogy; here he begins his reign, linking narrative to genealogical record.
