With a lower deck, a second deck in the middle and a third deck above. For behold, I will bring a great flood! You shall bring a pair of every
animal into the ark, a pair of each, of all living flesh. Male and female, to keep them alive with you. Of the birds after their kind, of the livestock after their kind. And of every creeping thing on the earth after its kind. A pair of every kind will come to you, to keep them alive. And you shall take with you some of all food that is eaten and gather it to yourself; and it will be for food for you, and for them.”
And Noah did all that God commanded him.
