Acts 10:5-6

When I was in Joppa, I visited the house of Simon the tanner by the seaside, ascended to the roof, and there prayed where Peter was praying when he saw the vision and heard the voice of the Spirit commanding him to go with the messengers who had already arrived from Cornelius. “Do you think it is the same house?” I have no reason to doubt. All the houses in Palestine are stone, consolidated by that wonderful calcareous cement, so they never decay. This house is all solid stone walls, floors, stairway and roof, so consolidated that it looks like a monolith throughout, not so much as a seam anywhere visible. The roof is simply a great solid, flat rock, looking as old as the native mountain strata.
