Acts 10:29 - Matthew Poole's English Annotations on the Holy Bible

Gainsaying, or delay. I ask therefore for what intent ye have sent for me? Peter did in a great measure know the business he came about, partly by the vision and its interpretation, partly by what he might have heard from them that Cornelius sent for him, unto whom Cornelius had declared the whole matter, as we find, Acts 10:8; yet Peter's question is but necessary, for to give Cornelius an opportunity to acquaint his friends, who were met there, with all that had passed.
