Numbers 19:14-19

ISV(i) 14 “This is the procedure to follow when a man dies in his tent: Everyone who enters the tent and everyone in it is to remain unclean for seven days. 15 Every open vessel that has no covering fastened around it is to be considered unclean. 16 Whoever is out in an open field and touches the body of someone who was killed by a sword, or a dead body, or someone’s bones, or a grave, he is to be considered unclean for seven days.
17 “Now as for the unclean, they are to take ashes from the burning sin offering, and pour running water on it inside a vessel. 18 A clean person is to take some hyssop, dip it in water, and then sprinkle it on the tent, on every vessel, and on whoever was there (that is, on whoever touched the bones, the killed person, or the dead body, including whoever dug the grave). 19 The clean person is to sprinkle the unclean person on the third day and seventh day and then he is to purify himself on the seventh day, wash his clothes, and bathe with water. He is to be considered clean at evening.
