'Inner chamber' in the Bible

Now she had an ambush abiding in the inner chamber. And she said to him, The Philistines are upon thee, Samson. And he broke the withes, as a string of tow is broken when it touches the fire. So his strength was not known.

So Delilah took new ropes, and bound him with it, and said to him, The Philistines are upon thee, Samson. And the ambushment was abiding in the inner chamber. And he broke them off his arms like a thread.
