John Gill Commentary Acts 14:8

"And at Lystra there sat a certain man, impotent in his feet, a cripple from his mother`s womb, who never had walked." — Acts 14:8 (ASV)

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.
