Who stedfastly beholding him - Fixing his eyes intently on him. See the notes on Acts 1:10.
And perceiving - How he perceived this is not said. Perhaps it was indicated by the ardor, 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 Icontium had doubtless also been heard of in Lystra.
Had faith to be healed - Compare Matthew 9:21-22, Matthew 9:28-29; Luke 7:50; Luke 17:19; Luke 18:42.
