And there sat a certain man at Lystra
 Where the apostle was preaching; and perhaps he sat there to beg, where there was a great concourse of people, and which might be in the open street: this man was 
 impotent in his feet;
 so weak, as not to be able to walk, and even to stand on them, and therefore is said to sit: 
 being a cripple from his mother's womb;
 he was born lame, as was the man cured by Peter, ( Acts 3:2 ) 
 who never had walked;
 these circumstances are mentioned, to show that his case was incurable by any human art, and to illustrate the following miracle.
