2 Kings 2:12

Then his servants approached and spoke to him and said, “My father, had the prophet spoken with you to do some great thing, would you not have done it? How much more then, when he says to you, ‘Wash, and be clean’?”

Now Elisha became sick with the illness of which he was to die. So Joash the king of Israel came down to him and wept over him and said, “My father, my father, the chariots of Israel and its horsemen!”
