and they shall be upon Aaron, and upon his sons, when they go into the tent of meeting, or when they come near the altar to minister in the holy place; lest they bring guilt upon themselves and die. This shall be a perpetual statute for him and for his descendants after him.
and the Lord said to Moses, “Tell Aaron your brother not to come at all times into the holy place within the veil, before the mercy seat which is upon the ark, lest he die; for I will appear in the cloud upon the mercy seat.
So keep my charge never to practice any of these abominable customs which were practiced before you, and never to defile yourselves by them: I am the Lord your God.”
And you shall bear no sin by reason of it, when you have offered the best of it. And you shall not profane the holy things of the people of Israel, lest you die.’ ”
