In it were all kinds of four-footed creatures and reptiles and birds of the air. Then he heard a voice saying, Get up, Peter; kill and eat. But Peter said, By no means, Lord; for I have never eaten anything that is profane or unclean. The voice said to him again, a second time, What God has made clean, you must not call profane. This happened three times, and the thing was suddenly taken up to heaven.
