Leviticus 16:11-14

“Aaron must bring the bull for his own sin offering. It will pay for his own sin and the sin of his whole family. He must kill the bull for his own sin offering. He must take a shallow cup full of burning coals from the altar in my sight. He must get two handfuls of incense completely ground up. The incense must smell sweet. He must take the cup and the incense behind the curtain. He must put the incense on the fire in my sight. The smoke from the incense will hide the cover of the ark where the tablets of the covenant law are kept. The cover is the place where sin is paid for. Aaron must burn the incense so that he will not die. He must dip his finger in the bull’s blood. He must sprinkle it on the front of the cover of the ark. He must sprinkle some in front of the cover. He must do it seven times.
