2 Kings 10:8-10

8When a messenger came and told him saying, “They have brought the heads of the king’s sons,” he said, “Put them in two heaps at the entrance of the gate until morning.”

9It came to pass in the morning that he went out and stood and addressed all the people, “You are innocent. Behold, I conspired against my master and killed him, but who struck down all these?

10Know then that not a word of Adonai will fall to the earth—which Adonai spoke about the house of Ahab—for Adonai has done what He spoke through His servant Elijah.”
