6 And Seth was a hundred and five years old when he became the father of Enosh: 7 And he went on living after the birth of Enosh for eight hundred and seven years, and had sons and daughters: 8 And all the years of Seth's life were nine hundred and twelve: and he came to his end. 9 And Enosh was ninety years old when he became the father of Kenan: 10 And after the birth of Kenan, Enosh went on living for eight hundred and fifteen years, and had sons and daughters: 11 And all the years of Enosh were nine hundred and five: and he came to his end.

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.
