Albert Barnes Commentary Acts 10:26

"But Peter raised him up, saying, Stand up; I myself also am a man." — Acts 10:26 (ASV)

Stand up, etc. This does not imply that Peter supposed that Cornelius intended to offer him religious reverence. It was practically saying to him, "I am nothing more than a man, as you are, and claim no right to such profound respects as these, but am ready in civil life to show you all the respect that is due."—Doddridge.
