Hebrews 9:12-13

12Christ went into the Most Holy Place on our behalf. He did this once, for all time. He did not take with him the blood of goats or young cows when he went in there. Instead, he took the blood of his own death to offer to God. In that way, he made us free from sin for ever.

13The old rules said that the priest must use the blood of goats or bulls to make people clean. Or he could burn a young cow and mix the ashes with water. He would then splash the blood or the ashes over the people who were unclean. Then those people became clean again in their bodies, and they could worship God.
