'Slain' in the Bible

Anyone {in the open field} who touches {one who has been slain}, or a corpse, or a bone of a person, or a burial site, he will be unclean for seven days.

A clean person will take hyssop and dip [it] into the water and sprinkle [it] on the tent and on all the objects and persons who were there, and on one who touched the bone, or the one slain, or the dead, or the burial site.

Look! [the] people will rise like the lion; he raises himself and will not lie down until he eats [the] prey and drinks the blood of the slain."

They killed the kings of Midian in addition to the ones they had slain: Evi and Rekem and Zur and Hur and Reba, the five kings of Midian; they also killed Balaam son of Beor by the sword.

And you, camp outside the camp seven days; all who killed a person and all who touched the slain purify yourselves on the third day and on the seventh day, you and your captives.
