On the very same day Noah and Noah’s sons, Shem, Ham, and Japheth, and Noah’s wife and the three wives of his sons with them, entered the ark— 14 they and every beast after its kind, all cattle 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. 15 And they went into the ark to Noah, two by two, of all flesh in which is the breath of life. 16 So those that entered, male and female of all flesh, went in as God had commanded him; and the Lord shut him in.
Genesis 7:13-16, NKJV
Then the Lord said to Noah, “Come into the ark, you and all your household, because I have seen that you are righteous before Me in this generation. 2 You shall take with you seven each of every clean animal, a male and his female; two each of animals that are unclean, a male and his female; 3 also seven each of birds of the air, male and female, to keep [a]the species alive on the face of all the earth. 4 For after seven more days I will cause it to rain on the earth forty days and forty nights, and I will [b]destroy from the face of the earth all living things that I have made.” 5 And Noah did according to all that the Lord commanded him.
