Numbers 19:15-17

New American Standard Bible

¹⁵ And every open container, which has no cover tied down on it, will be unclean. ^16 (A)Also, anyone who in the open field touches one who has been killed with a sword or one who has died naturally, or touches a human bone or a grave, will be unclean for seven days. ¹⁷ Then for the unclean person they shall take some of the ^[a]ashes of the ^[b]burnt ^[c](B)purification from sin and ^[d]running water shall be ^[e]added to them in a container.
