Hebrews 9:13, 19, 21

The blood of goats and bulls and the ashes of a heifer sprinkled on those who are ceremonially unclean sanctify them so that they are outwardly clean.

When Moses had proclaimed every command of the law to all the people, he took the blood of calves, together with water, scarlet wool and branches of hyssop, and sprinkled the scroll and all the people.

In the same way, he sprinkled with the blood both the tabernacle and everything used in its ceremonies.
