Even though Jesus was traveling with a group of people the leper breaks the law. Instead of keeping his distance he rushes to Jesus. You can imagine upon seeing him that others in Jesus party recoil. They may even run away for fear. There is a pause.
People are in shock.
Their space has been violated by this leper. Jesus stay put and looks upon the man with loving eyes, knowing what he is going through. With incredible compassion He reaches out and touches the man, perhaps on the face with a tender touch. Be made clean. At that very moment the leprosy leaves the man.
