'Upper' in the Bible

And she said to him, "Give me {a gift}; you have given me the land of the Negev, and give me also a spring of water." And Caleb gave to her the upper and lower spring.

and Ehud came to him [while] he [was] sitting alone in his cool upper room. And Ehud said, "I have a {message from God} for you." So he got up from his seat.

And Ehud went out the vestibule, and he closed the doors of the upper room and locked [them] behind him.

After he left, his servants returned. When they saw [that] the doors of the upper room [were] locked, {they thought}, "Surely he [is] {relieving himself} in the cool inner room."

And they waited so long they became embarrassed because he did not open the doors of the upper room. So they took the key and opened [the doors], and there their lord was lying on the ground dead.

But a certain woman threw an upper millstone on Abimelech's head and cracked open his skull.
