Genesis 7:1-6

1The LORD then said to Noah, “Go into the ark, you and your whole family, because I have found you righteous in this generation. 2Take with you seven pairs of every kind of clean animal, a male and its mate, and one pair of every kind of unclean animal, a male and its mate, 3and also seven pairs of every kind of bird, male and female, to keep their various kinds alive throughout the earth.

4Seven days from now I will send rain on the earth for forty days and forty nights, and I will wipe from the face of the earth every living creature I have made.”

5And Noah did all that the LORD commanded him. 6Noah was six hundred years old when the floodwaters came on the earth.
