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 beasts, and of beasts that are not clean, and of birds, and of everything that creepeth upon the ground,

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

And Noah builded an altar unto Jehovah, and took of every clean beast, and of every clean bird, and offered burnt-offerings on the altar.

Ye are the children of Jehovah your God: ye shall not cut yourselves, nor make any baldness between your eyes for the dead.

and he beholdeth the heaven opened, and a certain vessel descending, as it were a great sheet, let down by four corners upon the earth:

and that ye may make a distinction between the holy and the common, and between the unclean and the clean;

And they shall teach my people the difference between the holy and the common, and cause them to discern between the unclean and the clean.
