Numbers 19:18-20 The Voice (VOICE)
18 A person who is ritually pure should then dip a hyssop branch into the water and splash some water on the contaminated home—and on all the things in it and the people, too—or on the person who touched a corpse or some part of a dead person. 19 The ritually pure person must do this for the impure individual on the third and seventh days. Then he must purify himself, washing his body and clothes in water, so that he’s pure when it becomes evening on the seventh day.
20 Those who don’t so purify themselves shall be cast out of the community because they have scorned and polluted My holy place. Since the cleansing water hasn’t been splashed on them, they are impure.
