Genesis 7:12

went by pairs to Noah into the ship, male and female, as God commanded Noah.

After the seven days, the floodwaters came on the earth.

In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on that day all the fountains of the great deep burst open, and the sky’s windows opened.

In the same day Noah, and Shem, Ham, and Japheth—the sons of Noah—and Noah’s wife and the three wives of his sons with them, entered into the ship—

they, and every animal after its kind, all the livestock after their kind, every creeping thing that creeps on the earth after its kind, and every bird after its kind, every bird of every sort.

Pairs from all flesh with the breath of life in them went into the ship to Noah.
