and they shall be upon Aaron, and upon his sons, when they go in unto the tent of meeting, or when they come near unto the altar to minister in the holy place; that they bear not iniquity, and die: it shall be a statute for ever unto him and unto his seed after him.
And ye shall bear no sin by reason of it, when ye have heaved from it the best thereof: and ye shall not profane the holy things of the children of Israel, that ye die not.
and Jehovah said unto Moses, Speak unto Aaron thy brother, that he come not at all times into the holy place within the veil, before the mercy-seat which is upon the ark; that he die not: for I will appear in the cloud upon the mercy-seat.
and he shall put the incense upon the fire before Jehovah, that the cloud of the incense may cover the mercy-seat that is upon the testimony, that he die not:
Therefore shall ye keep my charge, that ye practise not any of these abominable customs, which were practised before you, and that ye defile not yourselves therein: I am Jehovah your God.
