'Sheet' in the Bible

and saw heaven open and something like a large linen sheet coming down, being lowered by its four corners to the ground.

This happened three times. Then the sheet was quickly taken back into heaven.

"I was in the town of Joppa praying when in a trance I saw a vision: Something like a large linen sheet descended down from heaven, lowered by its four corners, and it came right down to me.
