2 Kings 5:3, 8, 15

One day the girl said to her mistress, “I wish my master would go to see the prophet in Samaria. He would heal him of his leprosy.”

But when Elisha, the man of God, heard that the king of Israel had torn his clothes in dismay, he sent this message to him: “Why are you so upset? Send Naaman to me, and he will learn that there is a true prophet here in Israel.”

Then Naaman and his entire party went back to find the man of God. They stood before him, and Naaman said, “Now I know that there is no God in all the world except in Israel. So please accept a gift from your servant.”
