Genesis 7:1 WBT

¹  And the LORD said to Noah, Come thou and all thy house into the ark: for thee have I seen righteous before me in this generation.

²  Of every clean beast thou shalt take to thee by sevens, the male and his female: and of beasts that [are] not clean by two, the male and his female.

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.
