'Lower' in the Bible

Make a roof for the ark and finish it, leaving 18 inches from the top. Put a door in the side of the ark, and make lower, middle, and upper decks.

I will say to a young woman, 'Please lower your jar so I may drink.' May the one you have chosen for your servant Isaac reply, 'Drink, and I'll give your camels water too.' In this way I will know that you have been faithful to my master."
