[83] For indeed Seth was born when Adam was in his two hundred and thirtieth year, who lived :nine hundred and thirty years. Seth begat Enos in his two hundred and fifth year; who, when he had lived nine hundred and twelve years, delivered the government to Cainan his son, whom he had in his hundred and ninetieth year. He lived nine hundred and five years. Cainan, when he had lived nine hundred and ten years, had his son Malaleel, who was born in his hundred and seventieth year. This Malaleel, having lived eight hundred and ninety-five years, died, leaving his son Jared, whom he begat when he was in his hundred and sixty-fifth year. He lived nine hundred and sixty-two years; and then his son Enoch succeeded him, who was born when his father was one hundred and sixty-two years old. Now he, when he had lived three hundred and sixty-five years, departed and went to God; whence it is that they have not written down his death. Now Mathusela, the son of Enoch, who was born to him when he was one hundred and sixty-five years old, had Lamech for his son when he was one hundred and eighty-seven years of age; to whom he delivered the government, when he had retained it nine hundred and sixty-nine years. Now Lamech, when he had governed seven hundred and seventy-seven years, appointed Noah, his son, to be ruler of the people, who was born to Lamech when he was one hundred and eighty-two years old, and retained the government nine hundred and fifty years. These years collected together make up the sum before set down. But let no one inquire into the deaths of these men; for they extended their lives along together with their children and grandchildren; but let him have regard to their births only.
