Hebrews 9:13, 19, 21

Under the old system, the blood of goats and bulls and the ashes of a heifer could cleanse people’s bodies from ceremonial impurity.

For after Moses had read each of God’s commandments to all the people, he took the blood of calves and goats, along with water, and sprinkled both the book of God’s law and all the people, using hyssop branches and scarlet wool.

And in the same way, he sprinkled blood on the Tabernacle and on everything used for worship.
