A voice then directed Peter with the words, “Get up; kill and eat [one of them].”
He became hungry and wanted something to eat, but while lunch was being prepared he was overcome by a “trance” [i.e., a semiconscious, vision-like state]
It contained all kinds of four-footed animals, crawling [reptiles] and birds.
But Peter answered, “No, Lord, I cannot. I have never eaten any such ordinary or [ceremonially] unfit creatures.”
