When Methuselah had lived 187 years, he became the father of Lamech.
To Enoch was born Irad, and Irad was the father of Mehujael, and Mehujael was the father of Methushael, and Methushael was the father of Lamech.
Enoch walked faithfully with God; then he was no more, because God took him away.
After he became the father of Lamech, Methuselah lived 782 years and had other sons and daughters.
