2 Kings 5:8

that he sent to the king The prophets of Jehovah were now in no such peril as they had been in Ahab's days. Elisha has his house in the royal city, and has no fear of sending a message to the palace.

that there is a prophet in Israel i.e. a true messenger of the God who can kill and make alive. Cf. the words of the people (Luke 7:16) when our Lord raised the widow's son at Nain, -A great prophet is risen up among us, and God hath visited his people".
