Thematic Bible: For those who had recently killed someone in battle

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. You will purify yourselves and every garment and every object of hide and all the work of goats' hair, and every object of wood."

Only the gold and the silver, the bronze, the iron, the tin, and the lead-- everything that will go through the fire--you will pass through the fire, and it will be clean, and only in waters of impurity will it be purified. Whatever does not go into the fire you will pass through the waters. And you will wash your garments on the seventh day and be clean, and afterward you will come into the camp."
