Early in Joash’s reign, he ordered the Temple to be repaired, but after 23 years, nothing had been done. So he reformed Temple donations by having them place the money directly into a locked box, and the money to repair the Temple was collected in no time.
Joash also paid tribute to Hazael of Syria to keep him from raiding Jerusalem.
He reigned for 40 years and then two of his servants murdered him. His son Amaziah became king.
