Matthew 9:27-31

And as Jesus passed by from thence, two blind men followed him, crying out, and saying, Have mercy on us, thou son of David. And when he was come into the house, the blind men came to him: and Jesus saith unto them, Believe ye that I am able to do this? They say unto him, Yea, Lord. Then touched he their eyes, saying, According to your faith be it done unto you. And their eyes were opened. And Jesus strictly charged them, saying, See that no man know it. But they went forth, and spread abroad his fame in all that land.
