Matthew 9:27-30

27And as Jesus passed on thence, two blind [men] followed him, crying and saying, Have mercy on us, Son of David.

28And when he was come to the house, the blind [men] came to him. And Jesus says to them, Do ye believe that I am able to do this? They say to him, Yea, Lord.

29Then he touched their eyes, saying, According to your faith, be it unto you.

30And their eyes were opened; and Jesus charged them sharply, saying, See, let no man know it.
