Leviticus 16:12-13

12 And he shall take a a censer full of coals of fire from the altar before the  Lord, and two handfuls of sweet incense beaten small, and he shall bring it inside the veil 13  b and put the incense on the fire before the  Lord, that the cloud of the incense may cover c the mercy seat that is over the testimony, so that he does not die.
