Leviticus 16:12-14

¹²And he shall take a censer full of coals of fire from off the altar before Jehovah, and his hands full of sweet incense beaten small, and bring it within the veil:

¹³and he shall put the incense upon the fire before Jehovah, that the cloud of the incense may cover the mercy-seat that is upon the testimony, that he die not:

¹⁴and he shall take of the blood of the bullock, and sprinkle it with his finger upon the mercy-seat on the east; and before the mercy-seat shall he sprinkle of the blood with his finger seven times.
