And the Lord set a mark upon Cain, lest any finding him should kill him. What was that mark? It was a mark of blackness. That mark rested upon Cain and descended upon his posterity from that time until the present. Today there are millions of the descendants of Cain, through the lineage of Ham, in the world, and that mark of darkness still rests upon them. Though nearly six thousand years have passed and gone, this mark is visible to the whole human family.
