It is objected here that we have no Authority in Scripture to prove this Part of the Story; but I answer, 'tis not likely but that _Abel_, as well as _Cain_, being at Man's Estate long before this, had several Children by their own Sisters, for they were the only Men in the World who were allow'd the Marrying their own Sisters, there being no other Women then in the World; and as we never read of any of _Abel_'s Posterity, 'tis likewise as probable they were all murther'd, as that they should kill _Abel_ only, whose Sons might immediately fall upon _Cain_ for the Blood of their Father, and so the World have been involv'd in a Civil War as soon as there were two Families in it. But be it so or not, 'tis not doubted the Devil wrought with _Cain_ in the horrid Murther, or he had never done it; whether it was directly or by Agents is not material, nor is the Latter unlikely; and if the Latter, then there is no Improbability in the Story, for why might not he that made Use of the Serpent to tempt _Eve_, be as well supposed to make a Tool of some of _Cain_'s Sons or Grandsons to prompt him in the wicked Attempt of murthering his Brother? and why must we be oblig'd to bring in a Miracle or an Apparition into the Story, to make it probable that the _Devil_ had any Hand in it, when 'twas so natural to a degenerate Race to act in such a Manner? However it was, and by whatever Tool the _Devil_ wrought, 'tis certain that this was the Consequence, poor _Abel_ was butcher'd, and thus the _Devil_ made a second Conquest in God's Creation; for _Adam_ was now, as may be said, really Childless, for his two Sons were thus far lost, _Abel_ was killed, and _Cain_ was curst and driven out from the Presence of the Lord, and his Race blasted with him. It would be a useful enquiry here, and worthy our giving an Account of, could we come to a Certainty in it, namely, what was the Mark that God set upon _Cain_, by which he was kept from being fallen upon by _Abel_'s Friends or Relations? but as this does not belong to the _Devil_'s History, and it was God's Mark, not the _Devil_'s, I have nothing to do with it here. The _Devil_ had now gain'd his Point, the Kingdom of Grace, so newly erected, had been as it were extinct without a new Creation, had not _Adam_ and _Eve_ been alive, and had not _Eve_, tho' now 130 Years of Age, been a breeding young Lady, for we must suppose the Woman, in that State of Longevity, bare Children till they were seven or eight hundred Year old: This Teeming of _Eve_ peopled not the World so much as it restored the blessed Race; for tho' _Abel_ was kill'd _Cain_ had a numerous Offspring presently, which had _Seth_, (_Adam_'s third Son) never been born, would soon have replenish'd the World with People, such as they were; the Seed of a Murtherer, cursed of God, branded with a Mark of Infamy, and who afterwards fell all together in the universal Ruine of the Race by the Deluge.
