'Inner' in the Bible

When you arrive there, search out Jehu the son of Jehoshaphat the son of Nimshi, and go in and bid him arise from among his brothers, and bring him to an inner room.

Then it came about, as soon as he had finished offering the burnt offering, that Jehu said to the guard and to the royal officers, “Go in, kill them; let none come out.” And they killed them with the edge of the sword; and the guard and the royal officers threw them out, and went to the inner room of the house of Baal.
