Mark 2:4

And when they could not come nigh unto him for the press, they uncovered the roof where he was: and when they had broken it up, they let down the bed wherein the sick of the palsy lay.

When they could not come near to him for the crowd, they removed the roof where he was. When they had broken it up, they let down the mat that the paralytic was lying on.

And when they could not come nigh unto him for the crowd, they uncovered the roof where he was: and when they had broken it up, they let down the bed whereon the sick of the palsy lay.

and not being able to come near to him because of the multitude, they uncovered the roof where he was, and, having broken `it' up, they let down the couch on which the paralytic was lying,

Since they were unable to get to Jesus through the crowd, they uncovered the roof above Him, made an opening, and lowered the paralytic on his mat.
