Numbers 19:13-15

New Revised Standard Version Catholic Edition

¹³ All who touch a corpse, the body of a human being who has died, and do not purify themselves, defile the tabernacle of the Lord; such persons shall be cut off from Israel. Since water for cleansing was not dashed on them, they remain unclean; their uncleanness is still on them.

¹⁴ This is the law when someone dies in a tent: everyone who comes into the tent, and everyone who is in the tent, shall be unclean seven days. ¹⁵ And every open vessel with no cover fastened on it is unclean.
