That was how King Joash repaid Jehoiada for his loyalty—by killing his son. Zechariah’s last words as he died were, “May the LORD see what they are doing and avenge my death!”
In the spring of the year the Aramean army marched against Joash. They invaded Judah and Jerusalem and killed all the leaders of the nation. Then they sent all the plunder back to their king in Damascus.
Although the Arameans attacked with only a small army, the LORD helped them conquer the much larger army of Judah. The people of Judah had abandoned the LORD, the God of their ancestors, so judgment was carried out against Joash.
The Arameans withdrew, leaving Joash severely wounded. But his own officials plotted to kill him for murdering the son of Jehoiada the priest. They assassinated him as he lay in bed. Then he was buried in the City of David, but not in the royal cemetery.
The assassins were Jozacar, the son of an Ammonite woman named Shimeath, and Jehozabad, the son of a Moabite woman named Shomer.
The account of the sons of Joash, the prophecies about him, and the record of his restoration of the Temple of God are written in His son Amaziah became the next king.
