Numbers 31:21 WBT

¹⁹  And do ye abide without the camp seven days: whoever hath killed any person, and whoever hath touched any slain, purify [both] yourselves and your captives on the third day, and on the seventh day.

²⁰  And purify all [your] raiment, and all that is made of skins, and all work of goats' [hair], and all things made of wood.

²¹  And Eleazar the priest said to the men of war who went to the battle, This [is] the ordinance of the law which the LORD commanded Moses;

²²  Only the gold, and the silver, the brass, the iron, the tin, and the lead,

²³  Every thing that may abide the fire, ye shall make [it] go through the fire, and it shall be clean: nevertheless it shall be purified with the water of separation: and all that abideth not the fire ye shall make go through the water.
