The priest would place some of the blood on the horns of the altar of incense. This altar is located directly in front of the curtain that separates the holy place from the most holy place. Leviticus 16:19 explains the purpose of the act: “[To] cleanse it and consecrate it from the uncleannesses of the people of Israel.” The fact that the blood was brought to the holy of holies highlights the seriousness of the sin of Israel’s religious leader.
7 Le sacrificateur mettra du sang sur les cornes de l'autel des parfums odoriférants, qui est devant l'Eternel dans la tente d'assignation; et il répandra tout le sang du taureau au pied de l'autel des holocaustes, qui est à l'entrée de la tente d'assignation.
