'Upper' in the Bible

Next, I noticed six men coming from the direction of the upper gate which faces north, each with his war club in his hand. Among them was a man dressed in linen with a writing kit at his side. They came and stood beside the bronze altar.

Now the upper chambers were narrower, because the galleries took more space from them than from the lower and middle chambers of the building.

For they were in three stories and had no pillars like the pillars of the courts; therefore the upper chambers were set back from the ground more than the lower and upper ones.
