'Lower' in the Bible

Make a roof for the ark, and finish the walls to within one cubit from the top. Place the entrance in the side of the ark, and build a lower, a middle, and an upper deck.

May it be that the young woman to whom I ask, "Please, lower your jug so that I may drink,' responds, "Have a drink, and I'll water your camels as well.' May she be the one whom you have chosen for your servant Isaac. This is how I'll know that you have shown your gracious love to my master."
