Genesis 7:2-9

7:2 You must take with you seven of every kind of clean animal, the male and its mate, two of every kind of unclean animal, the male and its mate, 7:3 and also seven of every kind of bird in the sky, male and female, to preserve their offspring on the face of the earth. 7:4 For in seven days I will cause it to rain on the earth for forty days and forty nights, and I will wipe from the face of the ground every living thing that I have made.”

7:5 And Noah did all that the Lord commanded him.

7:6 Noah was 600 years old when the floodwaters engulfed the earth. 7:7 Noah entered the ark along with his sons, his wife, and his sons’ wives because of the floodwaters. 7:8 Pairs of clean animals, of unclean animals, of birds, and of everything that creeps along the ground, 7:9 male and female, came into the ark to Noah, just as God had commanded him.
