2 Kings 10:6, 9-10, 15-16

Then Jehu wrote a second letter, saying, “If you are on my side and will obey me, cut off the heads of your master’s sons and come to me at Jezreel tomorrow about this time.” Now the seventy sons of the king’s family were with the leading men of the city who were their guardians.

In the morning, Jehu went out and stood before the people and said to them, “You are innocent. Look, I made plans against my master and killed him. But who killed all these? You should know that everything the LORD said about Ahab’s family will come true. The LORD has spoken through his servant Elijah, and the LORD has done what he said.”

After Jehu left there, he met Jehonadab son of Recab, who was also on his way to meet Jehu. Jehu greeted him and said, “Are you as good a friend to me as I am to you?” Jehonadab answered, “Yes, I am.” Jehu said, “If you are, then give me your hand.” So Jehonadab gave him his hand, and Jehu pulled him into the chariot. “Come with me,” Jehu said. “You can see how strong my feelings are for the LORD.” So Jehu had Jehonadab ride in his chariot.
