The murderer is transmigrated into water. The mystical sign of this is
indicated in (Deut. xii. 16), "Ye shall pour it upon the earth as
water;" and the meaning is, he is continually rolling on and on without
any rest. Therefore let no man drink (direct) from a running tap or
spout, but from the hollow of his hands, lest a soul pass into him, and
that the soul of a wicked sinner.
