'Summer house' in the Bible

Then Ehud came in to him while he was seated by himself in his summer-house. And Ehud said, I have a word from God for you. And he got up from his seat.

Then Ehud went out into the covered way, shutting the doors of the summer-house on him and locking them.

Now when he had gone, the king's servants came, and saw that the doors of the summer-house were locked; and they said, It may be that he is in his summer-house for a private purpose.

And I have smitten the winter-house with the summer-house, And perished have houses of ivory, And consumed have been many houses, An affirmation of Jehovah!
