2 Kings 9:11-15

Now Jehu went out to the servants of his master, and one said to him, “Is everything well? Why did this crazy fellow come to you?” And he said to them, “You know very well the man and his talk.”

And they said, “It is a lie; tell us now.” And he said, “Such and such he said to me, saying, ‘This is what the Lord says: “I have anointed you king over Israel.” ’ ”

Then they hurried, and each man took his garment and put it under him on the bare steps, and blew the trumpet, saying, “Jehu is king!” Jehu Assassinates Jehoram (Joram)

So Jehu the son of Jehoshaphat the son of Nimshi conspired against Joram. Now Joram with all Israel was defending Ramoth-gilead against Hazael king of Aram,

but King Joram had returned to Jezreel to have himself healed of the wounds which the Arameans had inflicted on him when he fought Hazael king of Aram. So Jehu said to the other men, “If this is your intent, then let no one escape from the city to go tell about it in Jezreel.”
