Genesis 7:6

Also of the birds of the sky, seven and seven, male and female, to keep seed alive on the surface of all the earth.

In seven days, I will cause it to rain on the earth for forty days and forty nights. I will destroy every living thing that I have made from the surface of the ground.”

Noah did everything that the LORD commanded him.

Noah went into the ship with his sons, his wife, and his sons’ wives, because of the floodwaters.

Clean animals, unclean animals, birds, and everything that creeps on the ground

went by pairs to Noah into the ship, male and female, as God commanded Noah.
