The Lord said to Moses, Say to Aaron, your brother, that he may not come at all times into the holy place inside the veil, before the cover which is on the ark, for fear that death may overtake him; for I will be seen in the cloud on the cover of the ark.
And after the holy place and all its vessels have been covered up by Aaron and his sons, when the tents of the people go forward, the sons of Kohath are to come and take it up; but the holy things may not be touched by them for fear of death.
Then Moses put all this law in writing, and gave it to the priests, the sons of Levi, who take up the ark of the Lord's agreement, and to all the responsible men of Israel.
But the Lord sent destruction on seventy men of the people of Beth-shemesh for looking into the ark of the Lord; and great was the sorrow of the people for the destruction which the Lord had sent on them.
