And when they could not find by what way they might bring him in because of the multitude, they went upon the housetop, and let him down through the tiling with his couch into the midst before Jesus.

Cross-reference

Luke 19:4 shows Zacchaeus climbing a tree to see Jesus — both involve determined effort to get close to Jesus.

Mark 2:4 describes the roof being removed to lower the paralytic, matching the action in this verse.

Matthew 9:2 records the same healing but omits the roof detail — here Luke adds the method of access.
