Leviticus 16:13-15

13He must then put the incense on the fire before the Lord, and the cloud of incense will cover the atonement plate which is above the ark of the testimony, so that he will not die.

14Then he is to take some of the blood of the bull and sprinkle it with his finger on the eastern face of the atonement plate, and in front of the atonement plate he is to sprinkle some of the blood seven times with his finger.

15“He must then slaughter the sin offering goat which is for the people. He is to bring its blood inside the veil-canopy, and he is to do with its blood just as he did to the blood of the bull: He is to sprinkle it on the atonement plate and in front of the atonement plate.
