21 When Enoch had lived 65 years, he fathered Methuselah. 22 Enoch walked with God[1] after he fathered Methuselah 300 years and had other sons and daughters. 23 Thus all the days of Enoch were 365 years. 24 Enoch walked with God, and he was not,[2] for God took him.

25 When Methuselah had lived 187 years, he fathered Lamech. 26 Methuselah lived after he fathered Lamech 782 years and had other sons and daughters. 27 Thus all the days of Methuselah were 969 years, and he died.

Commentary on Genesis 5:21-24

(Read Genesis 5:21-24)

Enoch was the seventh from Adam. Godliness is walking with God: which shows reconciliation to God, for two cannot walk together except they be agreed, Hebrews 11:5. He had lived but 365 years, which, as men's ages were then, was but the midst of a man's days. God often takes those soonest whom he loves best; the time they lose on earth, is gained in heaven, to their unspeakable advantage. See how Enoch's removal is expressed: he was not, for God took him. He was not any longer in this world; he was changed, as the saints shall be, who are alive at Christ's second coming. Those who begin to walk with God when young, may expect to walk with him long, comfortably, and usefully. The true christian's steady walk in holiness, through many a year, till God takes him, will best recommend that religion which many oppose and many abuse. And walking with God well agrees with the cares, comforts, and duties of life.

Commentary on Genesis 5:25-32

(Read Genesis 5:25-32)

Methuselah signifies, 'he dies, there is a dart,' 'a sending forth,' namely, of the deluge, which came the year that Methuselah died. He lived 969 years, the longest that any man ever lived on earth; but the longest liver must die at last. Noah signifies rest; his parents gave him that name, with a prospect of his being a great blessing to his generation. Observe his father's complaint of the calamitous state of human life, by the entrance of sin, and the curse of sin. Our whole life is spent in labour, and our time filled up with continual toil. God having cursed the ground, it is as much as some can do, with the utmost care and pains, to get a hard livelihood out comfort us." It signifies not only that desire and expectation which parents generally have about their children, that they will be comforts to them and helpers, though they often prove otherwise; but it signifies also a prospect of something more. Is Christ ours? Is heaven ours? We need better comforters under our toil and sorrow, than the dearest relations and the most promising offspring; may we seek and find comforts in Christ.
