What Would You Do? Luke Chapter 7

Some of us have heard the term, he/she, "can't hold water," meaning they can't keep a secret.  How could Jesus expect a blind or deaf person, who can now see and hear not to tell how it happened?  What would you do?

Mark 7:36-37 Then He commanded them that they should tell no one; but the more He commanded them, the more widely they proclaimed it. And they were astonished beyond measure, saying, “He has done all things well. He makes both the deaf to hear and the mute to speak.”
