Leviticus 16:13-15

13He must put the incense on the burning material. It is in front of the Lord. The smoke will cover the lid of the Covenant Box. So he will not die.

14He must take with him blood from the bull. He must use his finger to shake the blood. He must shake it onto the lid of the Covenant Box. He must shake the blood in front of the lid of the Covenant Box. He must shake it seven times with his finger.

15Aaron must kill the goat for the sin offering. It is a gift from the people. He must take the blood behind the curtain. He must shake the blood on the lid of the Covenant Box as he did with the bull's blood. And he must shake the blood in front of the lid of the Covenant Box.
