'House top' in the Bible

Whoever is on the housetop must not go down to get the things out that are in his house.

The one who is on the housetop must not go down, or go in to get anything out of his house;

On that day, the one who is on the housetop and whose goods are in the house must not go down to take them out; and likewise the one who is in the field must not turn back.

On the next day, as they were on their way and approaching the city, Peter went up on the housetop about the sixth hour to pray.
