And the LORD spake unto Moses and unto Aaron saying, / Cut ye not off the tribe of the families of the Kohathites from among the Levites: / But thus do unto them, that they may live, and not die, when they approach unto the most holy things: Aaron and his sons shall go in, and appoint them every one to his service and to his burden: / But they shall not go in to see when the holy things are covered, lest they die.  -    Bible     Quotes
