His mother was named Athaliah. She was the granddaughter of Omri, king of Israel. Ahaziah lived his life following the example of Ahab's household, practicing what the LORD considered to be evil, just like the household of Ahab, because he was a son-in-law to Ahab's household.

Now the king's sons, totaling 70 men, were living with the leading men of the city, who were their guardians. When the letter from Jehu arrived, the city leaders arrested the king's sons, slaughtered all 70 of them, put their heads in baskets, and sent them to Jehu at Jezreel.

Jehu met up with the relatives of King Ahaziah of Judah. He asked them, "Who are you?" They answered, "We're Ahaziah's relatives, and we've come down to greet the king's sons and the sons of the queen mother."
