Numbers 19:12-13 ▼

12 He is to purify himself with the water on the third day and the seventh day; then he will be clean. But if he does not purify himself on the third and seventh days, he will not be clean.

13 Anyone who touches a body of a person who has died, and does not purify himself, defiles the tabernacle of the LORD. That person will be cut off from Israel. He remains unclean because the water for impurity has not been sprinkled on him, and his uncleanness is still on him.”
