4And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the LORD had respect unto Abel and to his offering:

2Of 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.3Of fowls also of the air by sevens, the male and the female; to keep seed alive upon the face of all the earth.4For 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 off the face of the earth.5And Noah did according unto all that the LORD commanded him.6And Noah was six hundred years old when the flood of waters was upon the earth.7And 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.8Of clean beasts, and of beasts that are not clean, and of fowls, and of every thing that creepeth upon the earth,

20And Noah builded an altar unto the LORD; and took of every clean beast, and of every clean fowl, and offered burnt offerings on the altar.
