Genesis 7:14-18

they and every animal according to its kind, and all the livestock according to their kind, and every crawling thing that crawls on the earth according to its kind, and every bird according to its kind, all sorts of birds.

So they went into the ark to Noah, by twos of all flesh in which there was the breath of life.

Those that entered, male and female of all flesh, entered as God had commanded him; and the Lord closed the door behind him.

Then the flood came upon the earth for forty days, and the water increased and lifted up the ark, so that it rose above the earth.

The water prevailed and increased greatly upon the earth, and the ark floated on the surface of the water.
