Genesis 7:2

Take with you seven pairs of all clean animals , the male and his mate , and a pair of the animals that are not clean , the male and his mate ,

Take 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,

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.
