Genesis 7:6-9

New Revised Standard Version Catholic Edition

⁶ Noah was six hundred years old when the flood of waters came on the earth. ⁷ And Noah with his sons and his wife and his sons’ wives went into the ark to escape the waters of the flood. ⁸ Of clean animals, and of animals that are not clean, and of birds, and of everything that creeps on the ground, ⁹ two and two, male and female, went into the ark with Noah, as God had commanded Noah.
