'House top' in the Bible

while their inhabitants, lacking strength, stand dismayed and confused. They were like vegetation out in the fields, and like green herbs just as grass that grows on a housetop dries out before it can grow.

Anyone who's on the housetop must not come down to get what is in his house,

The one who's on his housetop must not come down and go into his house to take anything out of it,

"The person who is on the housetop that day must not come down to get his belongings out of his house. The person in the field, too, must not turn back to what's left behind.
