John Gill Commentary Genesis 5:18

"And Jared lived a hundred sixty and two years, and begat Enoch:" — Genesis 5:18 (ASV)

And Jared lived a hundred and sixty-two years, and he
begot Enoch .
] Here the Septuagint agrees with the Hebrew text, and the Samaritan version differs, reading only sixty-two; but this can hardly be thought to be his first son at such an age.
