'Room' in the Bible

"Send everybody out of here," Amnon said. So everyone left the room. Amnon told Tamar, "Bring the food into my private bedroom, so I can eat it with you personally." So Tamar took the cakes she had prepared and brought them into the private bedroom for her brother Amnon.

The king then became very upset. He went up to the upper room over the gate and wept. As he went he said, "My son, Absalom! My son, my son, Absalom! If only I could have died in your place! Absalom, my son, my son!"

And say ye to Amasa, Art thou not of my bone, and of my flesh? God do so to me, and more also, if thou be not captain of the host before me continually in the room of Joab.

You've made room beneath me for my footsteps, and my feet didn't slip.
