Matthew 9:27-30 KJV

28 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 said unto him, Yea, Lord.
29 Then touched he their eyes, saying,According to your faith be it unto you.
30 And their eyes were opened; and Jesus straitly charged them, saying,See that no man know it.
