Hebrews 9:20-23

20When Moses did this, he said to the people, ‘This blood shows that God's agreement with you has authority.’

21In the same way, Moses threw some of the blood onto the tabernacle. He also caused blood to drop onto all the things that the priests used to serve God there.

22God's Law taught that blood was necessary to make almost everything clean. We see that God does not forgive people for their sins unless there is blood from a death.

23The tabernacle and the things that were in it needed animals' blood to make them clean. That was a picture of the true place in heaven where people worship God. But the true things in heaven need better sacrifices to make them clean than the sacrifices of animals.
