John Gill Commentary Acts 10:25

"And when it came to pass that Peter entered, Cornelius met him, and fell down at his feet, and worshipped him." — Acts 10:25 (ASV)

And as Peter was coming in
Not into the city of Caesarea, for his entrance there is mentioned before, but into the house of Cornelius:

Cornelius met him, and fell down at his feet ;
to testify his great affection for him, and reverence of him:

and worshipped [him] ;
not with a religious adoration, or with worship due to God; for that would have been contrary to his character as a devout man, and one that feared God; but with civil worship and respect, in which he might exceed just bounds, and therefore is reproved by Peter: nor could he take him for an angel of God, or for one sent immediately from heaven to him; for he had been informed who he was, and what he was, and from whence he came, and what he was to do.
