Genesis 7:1-7

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. 7And Noah and his sons and his wife and his sons’ wives entered the ark to escape the waters of the flood.
