Next, use a finger to sprinkle some of the blood on the place of mercy, which is on the lid of the sacred chest; then sprinkle blood seven times in front of the chest.
According to the Law of Moses, those people who become unclean are not fit to worship God. Yet they will be considered clean, if they are sprinkled with the blood of goats and bulls and with the ashes of a sacrificed calf.
Christ did not have to offer himself many times. He wasn't like a high priest who goes into the most holy place each year to offer the blood of an animal.
However, only the high priest could go into the second part of the tent, and he went in only once a year. Each time he carried blood to offer for his sins and for any sins that the people had committed without meaning to.
