A voice came to him, "Get up, Peter, kill and eat!" But Peter said, "By no means, Lord, for I have never eaten anything unholy and unclean." Again a voice came to him a second time, "What God has cleansed, no longer consider unholy." This happened three times, and immediately the object was taken up into the sky.
