(17) Fifteen years.--He came to the throne in the second year of Jehoash, who reigned sixteen years (2Kings 13:10), and reigned twenty-nine years (2Kings 14:2). The different data are thus self-consistent. Jehoash appears to have died very soon after his victory--perhaps in the following year.

Verse 17. - And Amaziah the son of Joash King of Judah lived after the death of Jehoash son of Jehoahaz King of Israel fifteen years. This note of time is based on ver. 2, which makes Amaziah begin to reign in the second year of Joash of Israel, and hold the throne for twenty-nine years. If he really began to reign in the fourth year of Joash, he would have survived him only thirteen years (see the comment on ver. 2).

14:15-22 Amaziah survived his conqueror fifteen years. He was slain by his own subjects. Azariah, or Uzziah, seems to have been very young when his father was slain. Though the years of his reign are reckoned from that event, he was not fully made king till eleven years afterwards.And Amaziah the son of Joash king of Judah lived after the death of Jehoash son of Jehoahaz king of Israel fifteen years. Which, with the fourteen he reigned contemporary with him, made the twenty nine years he reigned, 2 Kings 14:2. The Vulgate Latin version is, "twenty five years".
