John Gill Commentary Matthew 14:35

"And when the men of that place knew him, they sent into all that region round about, and brought unto him all that were sick," — Matthew 14:35 (ASV)

And when the men of the place had knowledge of him
Not merely by report, but by face, having seen, and heard him before; see (Luke 5:1) .

They sent out into all that country round about, and brought unto
him all that were diseased ;
which not only expresses their faith in him, that he was able to heal all their sick and diseased, were they ever so many; but also their affectionate regard to their fellow creatures and countrymen; and their care and diligence in sending messengers about to their respective cities, towns, and villages, and which must be attended with expense: for they neither spared cost nor pains, to do good to their country; in all which, they set an example worthy of imitation.
