[17] spake unto Moses and unto Aaron, saying, [18] Cut ye not off the tribe of the families of the Kohathites from among the Levites: [19] But thus do unto them, that they may live, and not die, when they approach unto the most Aaron and his sons shall go in, and appoint them every to his service and to his burden: [20] But they shall not go in to see when the holy things are covered, lest they die.
