Matthew Poole and continuators on Acts 28:9

9 So when this was done , others also which had diseases in the island, came, and were healed:

The fame of this Cure, wrought so suddenly, perfectly, and only with the laying on of Paul's hands, could not but spread far and near; especially being done upon the Governor: And men are usually very careful about their bodily health and welfare. So that their Diseases were blessed Occasions to bring them to the knowledg of God in Christ, whom Paul preached. And they might have perished eternally, if they had not perished (or been thus near unto perishing) temporally.
