Genesis 7:6, 8-13

Noah was six hundred years old when the great flood came on the earth.

Two of each animal, the male and female, clean and unclean, large and small, along with birds and crawling things, entered the ark with Noah as God had commanded. Then seven days later, massive floodwaters covered the earth. It started in the six hundredth year of Noah’s life, in the second month on the seventeenth day. On that day, all the fountains of the subterranean deep cracked open and burst up through the ground. Heaven’s floodgates were opened, and heavy rains fell on the earth for forty days and forty nights. On that very day, Noah and his wife, their sons, Ham, Shem, and Japheth, and their wives, entered safely into the ark.
