Adam Clarke on Acts 10:25

Fell down at his feet, and worshipped him - As Peter's coming was announced by an angel, Cornelius might have supposed that Peter himself was an angel, and of a superior order; seeing he came to announce what the first angel was not employed to declare: it was, probably, in consequence of this thought that he prostrated himself before Peter, offering him the highest act of civil respect; for there was nothing in the act, as performed by Cornelius, which belonged to the worship of the true God. Prostrations to superiors were common in all Asiatic countries. The Codex Bezae, and the later Syriac in the margin reads this verse differently from all other MSS. and versions; thus, But as Peter drew nigh to Caesarea, one of the servants ran before, and told that he was come: then Cornelius leaped up, and met him, and, falling at his feet, he worshipped him. This is a very remarkable addition, and relates circumstances that we may naturally suppose did actually take place.
