Numbers 19:16-18 ▼

16 And whosoever in the open field touches one who is slain with a sword, or a dead body or a bone of a man or a grave shall be unclean seven days.

17 And for an unclean person they shall take some of the ashes of the burnt sin offering and shall pour running water into it in a vessel;

18 And a clean person shall take hyssop and dip it in the water and sprinkle it upon the tent and upon all the vessels and upon the persons who were there and upon him who touched a bone or a slain person or one dead or a grave;
