What does 2 Kings 5:13 mean?

But his servants came up to him and said, 'Sir, if the prophet had told you to do something difficult, wouldn't you have done it? So why not just do this simple thing and wash, and see what happens?' 2 Kings 5:13 - Modern Text Bible

(Naaman's servants talk sense into him, pointing out that if he'd do something hard, why not try something easy? They encourage him to give it a shot.)
