Numbers 31:21 In-Context

19 and dwell ye without the tents seven days. He that slayeth a man, or toucheth a slain man, shall be cleansed in the third [day], and the seventh day; (and then stay ye away from the tents for seven days. He who killeth a man, or toucheth a dead man, must cleanse both himself, and his captives, on the third day, and on the seventh day;)

20 and of all the prey, whether it is cloth, or vessel, and anything made ready to things pertaining to use, of the skins and hairs of goats, and wood, it shall be cleansed. (and all the spoils, whether it is a cloak, or a vessel, or anything made out of skin, or of goat hair, or of wood, must also be made clean, or purified.)

21 And Eleazar, the priest, spake thus to the men of the host that fought, This is the commandment of the law, which the Lord commanded to Moses,

22 The gold, and silver, and brass, and iron, and tin, and lead,

23 and all thing that may pass by (the) flame, shall be purged by fire; soothly whatever thing may not suffer fire, shall be hallowed with the water of cleansing. (and all the things that can pass through the flame, shall be purified by fire; but whatever thing cannot survive the flame, shall be made clean with the water of cleansing, or of purification.)
