Albert Barnes Commentary Acts 14:9

"The same heard Paul speaking, who, fastening eyes upon him, and seeing that he had faith to be made whole," — Acts 14:9 (ASV)

Who stedfastly beholding him. Fixing his eyes intently on him. (See Barnes on Acts 1:10.)

And perceiving. It is not stated how he perceived this. Perhaps it was indicated by the fervor, humility, and strong desire depicted in his countenance. He had heard Paul, and perhaps the apostle had dwelt particularly on the miracles with which the gospel had been attested. The miracles performed also in Iconium had doubtless also been heard of in Lystra.

Had faith to be healed. Compare Barnes' notes on Matthew 9:21, Matthew 9:22, Matthew 9:28, Matthew 9:29; Luke 7:50; Luke 17:19; Luke 18:42.
