The next day about noon these men were coming near Joppa. Peter went up on the roof of the house to pray and became very hungry. While the food was being prepared, he fell sound asleep and had a vision. He saw heaven open, and something came down like a huge sheet held up by its four corners. In it were all kinds of animals, snakes, and birds. A voice said to him, "Peter, get up! Kill these and eat them." But Peter said, "Lord, I can't do that! I've never eaten anything that is unclean and not fit to eat." The voice spoke to him again, "When God says that something can be used for food, don't say it isn't fit to eat." This happened three times before the sheet was suddenly taken back to heaven.
