Numbers 31:25

²³everything that shall pass through the fire shall so be clean, nevertheless it shall be purified with the water of sanctification; and whatsoever will not pass through the fire shall pass through water.

²⁴And on the seventh day ye shall wash your garments, and be clean; and afterward ye shall come into the camp.

— Numbers 31:25 —

²⁶Take the sum of the spoils of the captivity both of man and beast, thou and Eleazar the priest, and the heads of the families of the congregation.

²⁷And ye shall divide the spoils between the warriors that went out to battle, and the whole congregation.
