Numbers 19:2; Numbers 19:17; Numbers 19:18

2 "This is the statute of the law that the LORD has commanded: Tell the people of Israel to bring you a red heifer without defect, in which there is no blemish, and on which a yoke has never come.

17 For the unclean they shall take some ashes of the burnt sin offering, and fresh water shall be added in a vessel.

18 Then a clean person shall take hyssop and dip it in the water and sprinkle it on the tent and on all the furnishings and on the persons who were there and on whoever touched the bone, or the slain or the dead or the grave.
