'Object' in the Bible

And he saw heaven opened and an object something like a large sheet coming down, being let down to the earth by its four corners,

And this happened three times, and immediately the object was taken up into heaven.

"I was in the city of Joppa praying, and in a trance I saw a vision--an object something like a large sheet coming down, being let down from heaven by its four corners, and it came to me.
