18 And Jared was a hundred and sixty-two years old when he became the father of Enoch: 19 And Jared went on living after the birth of Enoch for eight hundred years, and had sons and daughters: 20 And all the years of Jared's life were nine hundred and sixty-two: and he came to his end.

21 And Enoch was sixty-five years old when he became the father of Methuselah: 22 And after the birth of Methuselah, Enoch went on in God's ways for three hundred years, and had sons and daughters: 23 And all the years of Enoch's life were three hundred and sixty-five: 24 And Enoch went on in God's ways: and he was not seen again, for God took him.

Commentary on Genesis 5:6-20

(Read Genesis 5:6-20)

Concerning each of these, except Enoch, it is said, "and he died." It is well to observe the deaths of others. They all lived very long; not one of them died till he had seen almost eight hundred years, and some of them lived much longer; a great while for an immortal soul to be prisoned in a house of clay. The present life surely was not to them such a burden as it commonly is now, else they would have been weary of it. Nor was the future life so clearly revealed then, as it now under the gospel, else they would have been urgent to remove to it. All the patriarchs that lived before the flood, except Noah, were born before Adam died. From him they might receive a full account of the creation, the fall, the promise, and the Divine precepts about religious worship and a religious life. Thus God kept up in his church the knowledge of his will.

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.
