民数记 31:19

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;

You yourselves will have to keep outside the tent-circle for seven days, anyone of you who has put any person to death or come near a dead body; and on the third day and on the seventh day make yourselves and your prisoners clean.
