And they shall be on Aaron, and on his sons, when they come in to the tabernacle of the congregation, or when they come near to the altar to minister in the holy place; that they bear not iniquity, and die: it shall be a statute for ever to him and his seed 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, that he die not:
And the LORD said to Moses, Speak to Aaron your brother, that he come not at all times into the holy place within the veil before the mercy seat, which is on the ark; that he die not: for I will appear in the cloud on the mercy seat.
Therefore shall you keep my ordinance, that you commit not any one of these abominable customs, which were committed before you, and that you defile not yourselves therein: I am the LORD your God.
And you shall bear no sin by reason of it, when you have heaved from it the best of it: neither shall you pollute the holy things of the children of Israel, lest you die.
