Matthew 14:36

And besought him that they might only touch the hem of his garment: and as many as touched were made perfectly whole.

The sick begged to be permitted to touch only the border of His clothing, convinced that even that slight contact would bring them healing. Their reaching out to touch Him was an act of faith, while the healing power itself flowed from Him. All who touched were made completely well, so that their suffering was replaced with joy and thankfulness.
