Genesis 7:11-16

11In the six hundredth year of Noah’s life, on the seventeenth day of the second month—on that day all the springs of the great deep burst forth, and the floodgates of the heavens were opened.

12And rain fell on the earth forty days and forty nights. 13On that very day Noah and his sons, Shem, Ham and Japheth, together with his wife and the wives of his three sons, entered the ark. 14They had with them every wild animal according to its kind, all livestock according to their kinds, every creature that moves along the ground according to its kind and every bird according to its kind, everything with wings. 15Pairs of all creatures that have the breath of life in them came to Noah and entered the ark.

16The animals going in were male and female of every living thing, as God had commanded Noah. Then the LORD shut him in.
