Genesis 7:5 WBT

³  Of fowls of the air also by sevens, the male and the female; to keep seed alive on the face of all the earth.

⁴  For yet seven days, and I will cause it to rain upon the earth forty days and forty nights: and every living substance that I have made will I destroy from the face of the earth.

⁵  And Noah did according to all that the LORD commanded him.

⁶  And Noah [was] six hundred years old when the flood of waters was on the earth.

⁷  And Noah went in, and his sons, and his wife, and his sons' wives with him, into the ark, because of the waters of the flood.
