Genesis 7:6-11

6Noah was six hundred years old when the flood of waters came upon the earth. 7And Noah and his sons and his wife and his sonswives with him went into the ark to escape the waters of the flood. 8Of clean animals, and of animals that are not clean, and of birds, and of everything that creeps on the ground, 9two and two, male and female, went into the ark with Noah, as God had commanded Noah. 10And after seven days the waters of the flood came upon the earth.

11In the six hundredth year of Noah’s life, in the second month, on the seventeenth day of the month, on that day all the a  fountains of the great deep burst forth, and b  the windows of the heavens were opened.
