Ver. 5. "And all the days that Adam lived were nine hundred and thirty years: and he died."
Adam therefore lived to see the translation of Enoch: In whose translation a conquest was got over all the enemies of his soul and body: So Christ shall reign in and among his saints till all his enemies be destroyed. "The last enemy that shall be destroyed is death" (1 Cor 15:26); which shall be swallowed up when the members of that glorious head have put on incorruption, and their "mortal shall have put on immortality." Adam's reigning therefore until Enoch's translation, looks like a prophecy of the perfection of Christ's kingdom: For he shall reign till he hath "delivered up the kingdom to God, even the Father" (v 24): As Adam, till his Enoch was translated and took up to God.
Ver. 6. "And Seth lived an hundred and five years, and begat Enos."
Seth therefore stood by the truth of God, a long time, without much help or encouragement from man; which was a great trial to his spirit, and proof of the truth of his faith, and tended much to the perfection of his patience. Somewhat like this was that of Paul, who had no man stood with him when he stood before Nero.
Seth was set in the stead of Abel, to keep the gap against the children of hell; which, by the grace of God, he faithfully did, even till Enos was sent to his aid and assistance.
Seth therefore was the forlorn hope of the church in those days. So set of God to put check to the enemy, until the church was increased, and more able to defend herself from the outrage.
This therefore should teach the saints of God, especially those that are sent before, against the offspring of Cain, to stand their ground, and not to shrink like Saul, till God shall send others to take part with them (1 Sam 10:8; 13:8-14).
Thus David stood, as it were, by himself, against the wicked that was in his day; which made him cry, "Who will rise up for me against the evil doers," or who will stand up for me against the workers of iniquity? (Psa 94:16).
Ver. 7. "And Seth lived after he begat Enos eight hundred and seven years, and begat sons and daughters."
Hence also we may gather great encouragement who are set in the front of the army of the Lamb, against the army and regiment of Cain. Seth, saith the Spirit, was set in the stead of Abel, there as forlorn, to defend religion: Must he not now be swallowed up? Will the blood-hounds let him escape? Behold, therefore his life must be accounted a wonder! As was also that of Paul (1 Cor 6:9). But for Seth to stand eight hundred years against such a murderous crew, and yet to have his breath in his nostrils! Our times are in thy hands, and thou, Lord, "holdeth our soul in life" (Psa 66:9).
