Genesis 5:22

And Enoch walked with God after he begat Methuselah three hundred years, and begat sons and daughters:

1. Enoch had more sons and daughters after Methuselah was born.
2. Enoch lived at least another 300 years after Methuselah was born.
3. Enoch had a very close relationship with God during the 300 years after Methuselah was born.
