And he showed us how he had seen an angel in his house,.... The clause, "in his house", is very appropriately put; for since an angel had entered into his house, it could not be criminal in Peter, and the six brethren, to follow him.
In one place he is called a man, and in another place an angel; see Ac 10:3, because, though he was an angel, yet he appeared in the form of a man, as it was usual for angels to do; but whether Cornelius knew that he was an angel, is not certain, since he calls him a man; and not he, but Luke the historian, and Peter, who repeats the account of the vision, call him an angel; however, he looked upon him as an extraordinary person, as sent to him from God, and therefore obeyed the heavenly vision.
