Numbers 19:18-20 Modern English Version (MEV)
18 A clean person will take hyssop, and dip it in the water, and splash it on the tent, and on all the vessels, and on the people who were there, and on him that touched a bone, or one slain, or one dead, or a grave. 19 The clean person will splash on the unclean person on the third day and on the seventh day. And on the seventh day he shall purify himself, wash his clothes, and bathe in water; and he will be clean at evening. 20 But the man who is unclean and does not purify himself, that person will be cut off from among the assembly because he has defiled the sanctuary of the Lord. The water of purification has not been sprinkled on him. He is unclean.
