King Joash didn't remember the kindness that Zechariah's father Jehoiada had extended to him, but killed his son. While he was dying, he said, "May the Lord see and demand an account."
At the turn of the year, an Aramean army went to war against Joash. They entered Judah and Jerusalem and destroyed all the leaders of the people among them and sent all the plunder to the king of Damascus.
References for 2 Chronicles 24:23
Although the Aramean army came with only a few men, the Lord handed over a vast army to them because the people of Judah had abandoned the Lord God of their ancestors. So they executed judgment on Joash.
When the Arameans saw that Joash had many wounds, they left him. His servants conspired against him, and killed him on his bed, because he had shed the blood of the sons of Jehoiada the priest. So he died, and they buried him in the city of David, but they did not bury him in the tombs of the kings.
