TSK · Numbers 31:20

So Jacob told his household and all who were with him,“Get rid of the foreign gods you have among you. Purify yourselves and change your clothes.

“‘This is the law: When a man dies in a tent, anyone who comes into the tent and all who are in the tent will be ceremonially unclean seven days.

And whatever the unclean person touches will be unclean, and the person who touches it will be unclean until evening.’”
