Levítico 16:13

13 He is to put the incense on the fire before the Lord, and the smoke of the incense will conceal the atonement cover above the tablets of the covenant law, so that he will not die.

13 And let him put the perfume on the fire before the Lord so that the ark may be covered with a cloud of the smoke of the perfume, in order that death may not overtake him.
