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.

Cross-reference

Luke 5:19 is the parallel account of this same event, describing the same roof removal and lowering of the paralytic.

Matthew 9:2 is the parallel account of this healing, though it omits the roof removal detail, focusing instead on Jesus' response.
