Genesis 7:2-12

2 From every clean animal, take seven pairs, a male and his mate; and from every unclean animal, take one pair, a male and his mate;
3 and from the birds in the sky as well, take seven pairs, male and female, so that their offspring will survive throughout the earth.
4 In seven days from now I will send rain on the earth for forty days and forty nights. I will wipe off from the fertile land every living thing that I have made."
5 Noah did everything the LORD commanded him.
6 Noah was 600 years old when the floodwaters arrived on earth.
7 Noah, his sons, his wife, and his sons' wives with him entered the ark to escape the floodwaters.
8 From the clean and unclean animals, from the birds and everything crawling on the ground,
9 two of each, male and female, went into the ark with Noah, just as God commanded Noah.
10 After seven days, the floodwaters arrived on the earth.
11 In the six hundredth year of Noah's life, in the second month, on the seventeenth day—on that day all the springs of the deep sea erupted, and the windows in the skies opened.
12 It rained upon the earth forty days and forty nights.
