Charles Ellicott Commentary Acts 10:17

"Now while Peter was much perplexed in himself what the vision which he had seen might mean, behold, the men that were sent by Cornelius, having made inquiry for Simon`s house, stood before the gate," — Acts 10:17 (ASV)

While Peter doubted in himself...—A doubt might well arise whether the teaching of the vision went beyond its immediate scope. The Apostle might have admitted that it abrogated the old distinction between clean and unclean meats, and yet might hesitate to answer the question, “Did it do more than this?”
