Numbers 19:22

And whatsoever the unclean person toucheth shall be unclean; and the soul that toucheth it, the water of purification, shall be unclean until even. These rites of external purification were symbols of the inner, spiritual cleansing which should be found in all true believers. "The ashes of an heifer sprinkling the unclean sanctifieth to the purifying of the flesh; how much more shall the blood of Christ.. purge your conscience from dead works to serve the living God!" Hebrews 9:13. The water of purification is also a type of the water of Baptism, for by having our souls sprinkled from an evil conscience, we have boldness to enter into the Holiest by the blood of Jesus, Hebrews 10:19.
