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.
And all the days of Seth were nine hundred and twelve years, and he died. As his father Adam before him. Seth, according to Josephus (l), was a very good man, and brought up his children well, who trod in his steps, and who studied the nature of the heavenly bodies; and that the knowledge of these things they had acquired might not be lost, remembering a prophecy of Adam, that the world should be destroyed both by fire and by water, they erected two pillars, called Seth's pillars; the one was made of brick, and the other of stone, on which they inscribed their observations, that so if that of brick was destroyed by a flood, that of stone might remain; and which the above writer says continued in his time in the land of Siriad. The Arabic writers (m) make Seth to be the inventor of the Hebrew letters, and say, that when he was about to die he called to him Enos, Cainan, Mahalaleel, Jared, Enoch, their wives and children, and adjured them by the blood of Abel not to descend from the mountain where they dwelt, after the death of Adam, nor suffer any of their children to go to, or mix with any of the seed of Cain, which were in the valley; whom he blessed, and ordered by his will to serve the Lord, and then died in the year of his age nine hundred and twelve, on the third day of the week of the month Ab (which answers to part of July and part of August), A. M. 1142, and his sons buried him in the hidden cave in the holy mountain, and mourned for him forty days.
