THE ARK AND THE FLOOD "And this is how thou shalt make the ark" (Gen. 6:15). R. Shemiah taught: The Holy One, blessed be He, showed Noah with a finger and said to him, Like this and that shalt thou do to the ark. One hundred and fifty rooms were along the length at the left side of the ark, thirty-three rooms across the width in the side within, and thirty-three rooms in the side across the width on the outside; and ten compartments in the centre, which were for the storerooms for the food. And there were five protected cisterns on the right side of the ark, and fifty protected cisterns on the left side of the ark, and the openings for the water pipes opened and closed, and so was it in the lowest division; and so || on the second floor, and so on the third floor.
