Acts 10:9-12

9The next day, as they were on their journey and approaching the city, Peter went up on the housetop about the sixth hour to pray.

10And he became hungry and wanted something to eat, but while they were preparing it, he fell into a trance

11and saw the heavens opened and something like a great sheet descending, being let down by its four corners upon the earth.

12In it were all kinds of animals and reptiles and birds of the air.
