Leviticus 16:12-14

¹²Then he must take some burning coals from the bronze altar and put them in the incense burner. Then he must fill his hands with fragrant finely-ground incense. Then he must take the incense and the incense burner inside the curtain into the Very Holy Place of the Sacred Tent.

¹³There he must put the incense on the burning coals, with the result that a cloud of burning incense will rise up over the lid of the sacred chest. If he obeys these instructions, he will not die like Korah's two sons did because of offering incense incorrectly (OR, because of being in God's presence).

¹⁴Then he must dip his finger into the basin and sprinkle some blood on the lid of the sacred chest, and also sprinkle some blood seven times against the front of the chest.
