905. This spirit is called 'Afrira', ashes of dust. He has no offspring, nor fruit in the world, since he is made of ashes of dust. Though he is called by that name, he is not of the holy soil which bears fruit, called "dust (Heb. afrot) of gold" (Iyov 28:6), but of "the ashes (Heb. afar) of the burnt purification" (Bemidbar 19:17), FOR ASHES ARE CALLED 'DUST'. He is "the ashes of the burnt purification," the indication IN THIS VERSE, comes in two versions, the one because that spirit is included within the purification (Heb. chatat) of sin, which is the secret of the powerful serpent CALLED BY THAT NAME. The other is when the man commits sin (Heb. chatat) and strengthens the dust, so it rules the world.
