There was something about the stranger who walked with those two men, which fascinated them.  The location was a dusty road that led from Jerusalem to Emmaus.  It happened almost 2000 years ago.  Jesus of Nazareth had taught the multitudes for three years.  He had done some fantastic things. He had healed the lame and the blind.  He had taken a little boy's lunch and then fed a multitude of more than 5,000 men, to say nothing of the number of women and children.
