Leviticus 16:12-14

¹²And he shall take a censer full of coals of fire from off the altar before the Lord, and his handful of sweet incense beaten small, and carry (them) within the veil.

¹³And he shall put the sweet incense upon the fire before the Lord, and the cloud of incense will envelope the mercy seat which is over the testimony, that he may not die.

¹⁴And he shall take of the blood of the bullock, and sprinkle it with his finger upon the face of the mercy seat eastward, and before the mercy seat he shall sprinkle seven times of the blood with his finger.
