1 And the LORD said to Noah, “Come you and all your house into the ark; for I have seen your righteousness before me in this generation.”
2 “Of every clean beast you shall take seven male and seven female; and of the beasts that are not clean two, the male and his female:”
3 “of the birds also of the heavens, seven male and seven female, to keep seed alive upon the face of all the earth.”
4 “For in seven days I will cause it to rain upon the earth forty days and forty nights; and every living thing that I have made will I destroy from off the face of the earth.”
5 And Noah did according to all that the LORD commanded him.
6 And Noah was six hundred years old when the flood of waters was upon the earth.
7 And Noah went in, and his sons, and his wife, and his sons’ wives with him, into the ark, because of the waters of the flood.
8 Of the clean animals, and of animals that are not clean, and of birds, and of everything that moves upon the earth,
9 two by two they went into the ark to Noah, male and female, as God had commanded Noah.
10 And it came to pass after the seven days, that the waters of the flood were upon the earth.
11 In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on the that day were all the fountains of the great deep opened up, and the windows of heaven were opened.
12 And the rain was upon the earth forty days and forty nights.
13 On that day entered Noah, and Shem, and Ham, and Japheth, the sons of Noah, and Noah’s wife, and the three wives of his sons with them, into the ark;
14 they, and every beast after its kind, and all the cattle after their kind, and every moving thing that moves upon the earth after its kind, and every bird after its kind, every bird of every sort.
15 And they went into the ark with Noah, two by two, of all flesh wherein is the breath of life.
16 And they that went in[a], went in male and female of all flesh, as God commanded him; and the LORD shut him in.
17 And the flood was forty days upon the earth; and the waters increased and supported the ark, and it was lifted up above the earth.
18 And the waters rose and covered the earth; but the ark went upon the face of the waters.
19 And the waters prevailed exceedingly upon the earth; and all the high mountains that were under the whole heaven were covered.
20 Fifteen cubits upward did the waters prevail, and the mountains were covered.
21 And all flesh died that moved upon the earth: all the birds, and cattle, and beasts, and every moving thing that moved upon the earth, and every man:
22 all in whose nostrils was the breath of the spirit of life; all that was on dry land died.
23 And every living thing was destroyed that was upon the face of the ground, both man, and cattle, and creeping things, and birds of the heavens; and they were destroyed from the earth: and Noah only was left, and they that were with him in[a] the ark.
24 And the waters prevailed upon the earth a hundred and fifty days.
[16] again here and in multiple other places, referencing those animals that came to the ark but were not allowed to go inside because they did not come male and female according to their kind (for all flesh had become corrupted; see 6:12)
[23] This can be used to dispel the notion that anyone could have clung to the outside of the ark, or made any other boat, or found any other way to survive during the flood.
