THE TEMPLE in Jerusalem fell into disrepair within a century of the death of Solomon. The king who repaired it was a good man—mostly. 

Joash (or Jehoash), son of Ahaziah, reigned in Judah 835–796 BC. He was made king at age seven by the high priest Jehoiada and is credited with restoring the Temple—even pushing the priests, who seemed rather slow to make repairs even after they were ordered to do so. 

However, the account in 2 Chronicles 24 records that after the death of Jehoiada, Joash fell away and returned to the pagan gods of the Canaanites. Worse, he had the son of Jehoiada, Zechariah, murdered for calling him out! As a consequence, God allowed Judah to be defeated by a relatively small army from the neighboring Aramean kingdom of Damascus, and Joash was assassinated in his bed by two of his servants. 

We also discuss the death of Elisha in the northern kingdom of Israel, and why King Joash (same name, different king) failed to completely defeat the Arameans.
