Numbers 19:10-12

Revised Standard Version Catholic Edition

¹⁰ And he who gathers the ashes of the heifer shall wash his clothes, and be unclean until evening. And this shall be to the people of Israel, and to the stranger who sojourns among them, a perpetual statute.

¹¹ “He who touches the dead body of any person shall be unclean seven days; ¹² he shall cleanse himself with the water on the third day and on the seventh day, and so be clean; but if he does not cleanse himself on the third day and on the seventh day, he will not become clean.
