And who shall say that the wicked, disgusting mode of life, the practices deteriorating the physical and mental powers imputed to the Cainites, do not constitute what some may call a philosophical cause of the physical development of the mark of sin? Does not our own observation teach us that a single lifetime, spent in the practice of some degrading sins, leaves upon the person the evidence, the mark, the proof of such practice? We are under no compulsion of evidence or belief to suppose that the mark set upon Cain was the product of a moment; but the gradual result of his wicked practices, as a physical and moral cause. But allow the fact to have been that, in the case of Cain, the physical change was instantaneous, God had the power to institute in a moment what should thereafter be produced only by progression or inheritance. God created man; but, thereafter, man was born and became mature through the instrumentality only of physical causes. “The shew of their countenance doth witness against them; and they declare their sin as Sodom, they hide it not.” _Isa._ iii. 9. In fact, “The faces of them all gather blackness.” _Nahum_ ii. 10. But we know that the descendants of Ham were black; nor is it stated that any personal mark was placed upon him, although the name applied to his first-born son, “Cush,” signifies that he was black, giving proof that the colour was inherited; but from whom? Not from his father! “Can the _Ethiopian_ (כּוּשִׁי _Cushi_, _the Cushite_, _the black man_) change his skin?” The evidence forced on the mind leads to the conclusion that the descendants of Ham were black, not by the progressive operation of the laws of God on the course of sin which they doubtless practised, but that they were so at birth,—consequently an inheritance from parentage. And a further conclusion also is, that the wife of Ham must have been black, of the race of Cain, inheriting his _mark_, and that _that mark_ was black.
