2 Kings 8:13-15

13Hazael said, ‘I am only an ordinary man, sir. I am not more important than a dog! How could I ever do great things like that?’ Elisha answered, ‘The Lord has shown me that you will become the king of Syria.’

14Then Hazael left Elisha. He returned to his master, the king. King Ben-Hadad asked him, ‘What did Elisha say to you?’ Hazael replied, ‘He told me that you will surely get well again.’

15The next day, Hazael took a thick cloth. He used water to make it wet. Then he put it over the king's face so that he could not breathe. So King Ben-Hadad died. Hazael became king of Syria after him.
