'Clean' in the Bible

of all the clean beasts thou dost take to thee seven pairs, a male and its female; and of the beasts which are not clean two, a male and its female;

of the clean beasts and of the beasts that are not clean, and of the fowl, and of every thing that is creeping upon the ground,

And Noah buildeth an altar to Jehovah, and taketh of every clean beast, and of every clean fowl, and causeth burnt-offerings to ascend on the altar;
