Genesis 7:1, 7-9

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.

So Noah, with his sons, his wife, and his sons’ wives, went into the ark because of the waters of the flood. Of clean animals, of animals that are unclean, of birds, and of everything that creeps on the earth, two by two they went into the ark to Noah, male and female, as God had commanded Noah.
