This is what you should do to make them clean: Sprinkle the cleansing water on them, and have them shave their bodies and wash their clothes so they will be clean.
So what do you think should be done to those who do not respect the Son of God, who look at the blood of the agreement that made them holy as no different from others’ blood, who insult the Spirit of God’s grace? Surely they should have a much worse punishment.
First, Moses told all the people every command in the law. Next he took the blood of calves and mixed it with water. Then he used red wool and a branch of the hyssop plant to sprinkle it on the book of the law and on all the people.
Now that your obedience to the truth has purified your souls, you can have true love for your Christian brothers and sisters. So love each other deeply with all your heart.
