Mark 2:4

They uncovered the roof - The houses in the east are generally made flat-roofed, that the inhabitants may have the benefit of taking the air on them; they are also furnished with battlements round about, Deuteronomy 22:8 ; Judges 16:27 ; and 2 Samuel 11:2 , to prevent persons from falling off; and have a trap door by which they descend into the house. This door, it appears, was too narrow to let down the sick man and his couch; so they uncovered the roof, removed a part of the tiles; and having broken it up, taken away the laths or timber, to which the tiles had been attached, they then had room to let down the afflicted man. See Luke 5:19 , and on Matthew 10:27 ; (note); Matthew 24:17 ; (note).
