Lamech signifieth poor, or smitten; wherefore I doubt that the apostacy that you read of in the next chapter, began either in the days of, or by, this man: he being, as it seems, more dry and void of grace than those that went before him; poor, or smitten.
Hence note, That faith and godliness, though often it goeth from the father to the son, as from Seth to Enos, and from him to Cainan, yet it is not tied here, but runs according to electing love, as also do the fruits thereof.
Ver. 26, 27. "And Methuselah lived after he begat Lamech seven hundred eighty and two years, and begat sons and daughters. And all the days of Methuselah were nine hundred sixty and nine years, and he died."
Methuselah, the spoiling of death, is the longest liver in the world; yet he died in the year that the flood was upon the earth; not by the flood, but by the course of nature, as also did Lamech his son, for the wicked reprobate only was swept away by that, according to the apostle Peter. Ver. 28, 29. "And Lamech lived an hundred eighty and two years, and begat a son: and he called his name Noah, saying, This same shall comfort us concerning our work and toil of our hands, because of the ground which the Lord hath cursed."
"And he called his name Noah." Noah signifieth rest; his name was therefore according to his work, for he was a preacher of righteousness, which giveth rest to all that embraceth it. Besides, it was he that prepared the ark, the place of rest to the church of God.
"This same shall comfort us concerning our work and toil of our hands, because of the ground which the Lord hath cursed."
These words seem to carry in them, repentance for the apostacy that before was mentioned. "This same shall comfort us," by restoring the church to her former rest, and by delivering us from the "toil of our hands"; for sin once admitted of in the church, is not without much toil extirpated, and driven forth of the same; yea sometimes it getteth such footing and root, that it cannot again be purged and destroyed, but by breaking the very being of the church where it is. Thus it was as to the case in hand, and is signified also by pulling down the house in which the leprosy was (Lev 14:43-45). Yea Ephesus itself was almost thus far infected, had not a threatening prevented (Rev 2:1-3).
"Because of the ground which the Lord hath cursed." The Lord did curse it for the sin of Adam: He also renewed the curse to Cain, because he was guilty of the blood of his brother. I incline also to think, that the curse here mentioned, is the first, reiterated for the grievous apostacy of this congregation; according to that which is written, "If ye walk contrary unto me," "I will punish you seven times more": "I will bring seven times more plagues upon you, according to your sins" (Lev 26:18-21).
Ver. 30. "And Lamech lived after he begat Noah, five hundred ninety and five years, and begat sons and daughters." Wherefore Lamech heard the preaching of Noah, who was the only minister of God in those days, to recover the church to repentance from their apostacy, which also he did in some good measure effect, while he condemned, the world for their unbelief (Heb 11:7).
Ver. 31. "And all the days of Lamech were seven hundred seventy and seven years: and he died." He died five years before the flood. Methuselah therefore was the longest liver of those godly that fell on the other side the flood, for he died not before the very year the flood came, not by the water, but before. The righteous is taken away from the evil to come; though, as the prophet saith, no man of the wicked laid it to heart.
