Genesis 5:7 Meaning and Commentary

Genesis 5:7

And Seth lived, after he begat Enos, eight hundred and
seven years
The Septuagint version makes the same mistake in the numbers of Seth as of Adam, giving him two hundred and five years before the birth of Enos, and but seven hundred and seven years after: and begat sons and daughters;
very probably both before and after Enos was born; but how many is not said.
