Numbers 19:12-13 He must purify himself with the water on the third day and on 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.

MSB⁽ⁱ⁾ ¹² He must purify himself with the water on the third day and on 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 human corpse and fails to purify himself defiles the tabernacle of the LORD. That person must be cut off from Israel. He remains unclean, because the water of purification has not been sprinkled on him, and his uncleanness is still on him.
