Genesis 5:13-16

Then Kenan lived eight hundred and forty years after he became the father of Mahalalel, and he had other sons and daughters. So all the days of Kenan were nine hundred and ten years, and he died. Mahalalel lived sixty-five years, and became the father of Jared. Then Mahalalel lived eight hundred and thirty years after he became the father of Jared, and he had other sons and daughters.
