Genesis 7:2

Treasury of Scripture Knowledge

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.

Of clean animals and animals that are not clean and birds and everything that creeps on the ground,

And of every living thing of all flesh, you shall bring two of every kind into the ark, to keep them alive with you; they shall be male and female.

Then Noah built an altar to the Lord, and took of every clean animal and of every clean bird and offered burnt offerings on the altar.

“You are the sons of the Lord your God; you shall not cut yourselves nor shave your forehead for the sake of the dead.

and he *saw the sky opened up, and an object like a great sheet coming down, lowered by four corners to the ground,

and so as to make a distinction between the holy and the profane, and between the unclean and the clean,

Moreover, they shall teach My people the difference between the holy and the profane, and cause them to discern between the unclean and the clean.
