Numbers 31:19

“All of you who have killed a person or touched the dead are to remain outside the camp for seven days. On the third day and the seventh day you are to purify both yourselves and your captives.”

“And do ye abide without the camp seven days: whosoever hath killed any person, and whosoever hath touched any slain, purify both yourselves and your captives on the third day, and on the seventh day.”

“And encamp ye without the camp seven days: whosoever hath killed any person, and whosoever hath touched any slain, purify yourselves on the third day and on the seventh day, ye and your captives.”

“`And ye, encamp ye at the outside of the camp seven days--any who hath slain a person, and any who hath come against a pierced one, ye cleanse yourselves on the third day, and on the seventh day--ye and your captives;”
