Acts 10:9-11

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

¹⁰He then became hungry and wanted something to eat, but while the people were cooking some food, he was given a vision,

¹¹and he saw the sky open and a certain container descending, something like a large sheet coming down to the earth, let down by its four corners.
