Gen 7: 8-9
Pairs of clean and unclean animals, of birds and of all creatures
that move along the ground, 9 male and female, came to Noah and
entered the ark, as God had commanded Noah
trying to keep it simple mah, 
ps... i know in verse 1-4, it said 7 of each kind (actually its
7pairs of each kind)
1 The LORD then said to Noah, "Go into the ark, you and your whole
family, because I have found you righteous in this generation. 2
Take with you seven [a] of every kind of clean animal, a male and
its mate, and two of every kind of unclean animal, a male and its
mate, 3 and also seven of every kind of bird, male and female, to
keep their various kinds alive throughout the earth. 4 Seven 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."
