Albert Barnes Commentary 2 Kings 4:10

"Let us make, I pray thee, a little chamber on the wall; and let us set for him there a bed, and a table, and a seat, and a candlestick: and it shall be, when he cometh to us, that he shall turn in thither." — 2 Kings 4:10 (ASV)

A little chamber on the wall - The room probably projected like a balcony beyond the lower apartments, which is a common arrangement in the East.

A stool - This should be translated as “a chair.” The presence of a “chair” and “table,” which were unusual in the sleeping rooms of the East, indicates that the prophet was expected to use his apartment for study and retirement, not only as a sleeping chamber.
