Acts 10:9-15

The next day, as they were on their way and were approaching the city, Peter went up on the roof of the house about the sixth hour (noon) to pray, but he became hungry and wanted something to eat. While the meal was being prepared he fell into a trance; and he saw the sky opened up, and an object like a great sheet descending, lowered by its four corners to the earth, and it contained all kinds of four-footed animals and crawling creatures of the earth and birds of the air. A voice came to him, “Get up, Peter, kill and eat!” But Peter said, “Not at all, Lord, for I have never eaten anything that is common (unholy) and [ceremonially] unclean.” And the voice came to him a second time, “What God has cleansed and pronounced clean, no longer consider common (unholy).”
