Numbers 19:18 NIrV

[18] Then a man who is ‘clean’ must dip branches of a hyssop plant in the water. He must sprinkle the tent with it. Everything that belongs to the tent must be sprinkled with it. The people in the tent must also be sprinkled. Anyone who has touched a human bone or a grave must be sprinkled. So must anyone who has touched someone who has been killed. And so must anyone who has touched someone who has died a natural death.
