Genesis 7:1-10

Then the LORD said to Noah, “I have seen that you are the best person among the people of this time, so you and your family can go into the boat. Take with you seven pairs, each male with its female, of every kind of clean animal, and take one pair, each male with its female, of every kind of unclean animal. Take seven pairs of all the birds of the sky, each male with its female. This will allow all these animals to continue living on the earth after the flood. Seven days from now I will send rain on the earth. It will rain forty days and forty nights, and I will wipe off from the earth every living thing that I have made.” Noah did everything the LORD commanded him. Noah was six hundred years old when the flood came. He and his wife and his sons and their wives went into the boat to escape the waters of the flood. The clean animals, the unclean animals, the birds, and everything that crawls on the ground came to Noah. They went into the boat in groups of two, male and female, just as God had commanded Noah. Seven days later the flood started.
