Genesis 6:12-14, 19-20, 22

When God saw that everyone on the earth did only evil, he said to Noah, “Because people have made the earth full of violence, I will destroy all of them from the earth. Build a boat of cypress wood for yourself. Make rooms in it and cover it inside and outside with tar.

Also, you must bring into the boat two of every living thing, male and female. Keep them alive with you. Two of every kind of bird, animal, and crawling thing will come to you to be kept alive.

Noah did everything that God commanded him.
