Acts 10:9-12

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

10Then he became very hungry and wanted to eat; but while they made ready, he fell into a trance

11and saw heaven opened and an object like a great sheet bound at the four corners, descending to him and let down to the earth.

12In it were all kinds of four-footed animals of the earth, wild beasts, creeping things, and birds of the air.
