“Now the vpper-chambers were shorter: for the galleries were higher then these, then the lower, and then the middlemost of the building.”
1611 King James Version (KJV)
42:5 Shorter - At first view it should seem to refer to the length, but indeed it refers to the height of the chambers, of which the lowest chamber was highest, the second lower pitched than the first, yet of greater height than the uppermost between the floor and ceiling.
