Matthew 9:27-31 NIV
As Jesus went on from there, two blind men followed him, calling out, “Have mercy on us, Son of David!”
When he had gone indoors, the blind men came to him, and he asked them, “Do you believe that I am able to do this?”
“Yes, Lord,” they replied.
Then he touched their eyes and said, “According to your faith let it be done to you”; and their sight was restored. Jesus warned them sternly, “See that no one knows about this.” But they went out and spread the news about him all over that region.
