They shall be on Aharon, and on his sons, when they go in to the tent of meeting, or when they come near to the altar to minister in the holy place; that they don't bear iniquity, and die: it shall be a statute forever to him and to his descendants after him.
and he shall put the incense on the fire before the LORD, that the cloud of the incense may cover the mercy seat that is on the testimony, so that he will not die.
and the LORD said to Moshe, *Tell Aharon your brother, not to come at all times into the Most Holy Place within the veil, before the mercy seat which is on the ark; lest he die: for I will appear in the cloud on the mercy seat.
Therefore you shall keep my charge, that you do not practice any of these abominable customs, which were practiced before you, and that you do not defile yourselves with them: I am the LORD your God.'*
You shall bear no sin by reason of it, when you have heaved from it the best of it: and you shall not profane the holy things of the children of Yisra'el, that you not die.
