2 Kings 8:14

HAZAEL RETURNED TO THE KING; LIED TO HIM; AND ASSASSINATED HIM THE NEXT DAY

"Then he departed from Elisha, and came to his master; who said unto him, What said Elisha to thee? And he answered, He told me that thou wouldest surely recover. And it came to pass on the morrow, that he took the coverlet, and dipped it in water, and spread it on his face, so that he died: and Hazael reigned in his stead."

"He took the coverlet ... and spread it on his face, so that he died" (2 Kings 8:15). "The noun translated `coverlet' is otherwise unknown";[20] and the opinions of scholars that it was "a mosquito net"[21] or maybe "a pillow"[22] are of no consequence. Whatever it was, it was an effective instrument by which Hazael suffocated Benhadad, the king of Syria.
