And it shall be upon Aaron to minister: and his sound shall be heard when he goeth in unto the holy place before Yahweh, and when he cometh out, that he die not.
And Yahweh said unto Moses, Speak unto Aaron thy brother, that he come not at all times into the holy place within the vail before the mercy seat, which is upon the ark; that he die not: for I will appear in the cloud upon the mercy seat.
