Genesis 5:10

And Enos lived after he begat Cainan eight hundred and fifteen years, and begat sons and daughters:

And Enos lived, after he begat Cainan, eight hundred and fifteen years,.... The Septuagint version is seven hundred and fifteen; the hundred which is wanting is to be supplied from the preceding verse, which in that version has an hundred too much:

and begat sons and daughters; others besides Enos, as very likely he had before he was born.
