Adam Clarke on Acts 9:35

All that dwelt in Lydda and Saron saw him - Saron was that champaign country that lay between Joppa and Lydda. The long affliction of this man had been well known; and his cure, consequently, became a subject of general examination: it was found to be real. It was known to have been performed by the grace and mercy of Christ; and the consequence of all this conviction was that all these people became Christians.
