'Levels' in the Bible

You shall make a roof in the ship, and you shall finish it to a cubit upward. You shall set the door of the ship in its side. You shall make it with lower, second, and third levels.

the thresholds, the beveled windows, and the balconies all around with their three levels opposite the threshold—were overlaid with wood on all sides. They were paneled from the ground to the windows (but the windows were covered),

And the upper chambers narrowed, for [the] galleries took away [space] from them more than [they took] from the lower [levels] and more than [they took] from the middle [level] [in the] building.
