“The one on the housetop
Must not go down
What is in his house.”
ὁ ἐπὶ τοῦ δώματος μὴ καταβάτω ἆραι τὰ ἐκ τῆς οἰκίας αὐτοῦ,
This is almost word for word in Mark, chapter 13:15, but not in Luke. During this end times, the people on the housetop or roofs of their houses (ὁ ἐπὶ τοῦ δώματος) should not go down (μὴ καταβάτω) to take things out of their houses (ἆραι τὰ ἐκ τῆς οἰκίας αὐτοῦ). It would be useless to do so, as the world was coming to an end.
