'Roof Chamber' in the Bible

Ehud came to him while he was sitting alone in his cool roof chamber. And Ehud said, “I have a message from God for you.” And he arose from his seat.

Then Ehud went out into the vestibule and shut the doors of the roof chamber behind him, and locked them.

When he had gone out, his servants came and looked, and behold, the doors of the roof chamber were locked; and they said, “He is only relieving himself in the cool room.”

They waited until they became anxious; but behold, he did not open the doors of the roof chamber. Therefore they took the key and opened them, and behold, their master had fallen to the floor dead.

Now when Daniel knew that the document was signed, he entered his house (now in his roof chamber he had windows open toward Jerusalem); and he continued kneeling on his knees three times a day, praying and giving thanks before his God, as he had been doing previously.
