The priest was not required to enter into the holy place in order to sprinkle the blood on the curtain or the altar of incense. This indicates that no defilement had taken place in the sanctuary, and thus there is no need for blood there. All activity takes place at the altar of burnt offering in the courtyard of the tabernacle.
25 Le sacrificateur prendra avec son doigt du sang de la victime expiatoire, il en mettra sur les cornes de l'autel des holocaustes, et il répandra le sang au pied de l'autel des holocaustes.
