Jehu found the brothers of Ahaziah king of Judah and said, “Who are you?” And they said, “We are brothers of Ahaziah, and we have come down to visit the sons of the king and the sons of the queen mother.”
Then he left there and found Jehonadab son of Rekab coming to meet him. He greeted him and said to him, “Is your heart right with me, as my heart is with yours?” And Jehonadab said, “It is.” “If it is, give me your hand.” So he gave him his hand, and he pulled him up to him into the chariot.
Then he wrote a second letter to them, saying, “If you belong to me and will obey me, take the heads of your master’s sons and come to me at Jezreel at this time tomorrow.” Now the king’s sons, seventy men, were with the great men of the city who brought them up.

And it happened that when Jehu was acting in judgment with the house of Ahab that he found the rulers of Judah and the sons of the brothers of Ahaziah, who were serving Ahaziah, and Jehu killed them.
eighty men came from Shechem, from Shiloh, and from Samaria, having their beards shaven, and their clothes torn, and their bodies gashed, with offerings and incense in their hands to bring them to the house of the Lord.
