Leviticus 16:12-13

BSB(i) 12 Then he must take a censer full of burning coals from the altar before the LORD, and two handfuls of finely ground fragrant incense, and take them inside the veil. 13 He is to put the incense on the fire before the LORD, and the cloud of incense will cover the mercy seat above the Testimony, so that he will not die.
