'Upper' in the Bible

Behold, six men [angelic beings] came from the direction of the Upper Gate, which faces north, each with his battle-axe in his hand; and among them was a certain man clothed in linen, with a scribe’s writing case at his side. They entered and stood beside the bronze altar.

Now the upper chambers were smaller because the galleries took away more space from them than from the chambers on the lower and middle stories of the building;

for they were in three stories and did not have pillars like the pillars of the [outer] courtyards; therefore the upper chambers were set back from the ground more than the lower and the middle ones.
