Acts 10:9-16

Now on the morrow, as they were on their journey, and drew nigh unto the city, Peter went up upon the housetop to pray, about the sixth hour: and he became hungry, and desired to eat: but while they made ready, he fell into a trance; and he beholdeth the heaven opened, and a certain vessel descending, as it were a great sheet, let down by four corners upon the earth: wherein were all manner of fourfooted beasts and creeping things of the earth and birds of the heaven. And there came a voice to him, Rise, Peter; kill and eat. But Peter said, Not so, Lord; for I have never eaten anything that is common and unclean. And a voice came unto him again the second time, What God hath cleansed, make not thou common. And this was done thrice: and straightway the vessel was received up into heaven.
