Nehemiah 13:5

He had prepared for him a great chamber By breaking down the partitions, it is probable, between several little chambers, where holy things were laid, and by removing the things which were in them, he had prepared one large room for Tobiah's reception, when he came to Jerusalem. This, no doubt, he had furnished for his use, and here Tobiah lodged, in order that he and the high-priest might have more free and secret communication with each other, this being a place where the people might not come.
