Acts 10:9-12

9Now 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:

10and he became hungry, and desired to eat: but while they made ready, he fell into a trance;

11and he beholdeth the heaven opened, and a certain vessel descending, as it were a great sheet, let down by four corners upon the earth:

12wherein were all manner of fourfooted beasts and creeping things of the earth and fowls of the heaven.
