בראשית, פרק ה׳, פסוק כ״ה

The ancestral chain leading up to the great flood continues to unfold, marking the steady transfer of human legacy from one generation to the next. At this stage in history, Methuselah establishes the next link in the family line by fathering a son. Methuselah's specific age at the time of this birth can be viewed through a unique chronological lens. This lifespan milestone is understood as being composed of thirty-six distinct units of sixty months, with an additional seven years added to the total [קאסוטו].

The son born to Methuselah is named Lamech. Interestingly, this name is not new to the narrative, having already appeared earlier in the lineage of Cain. While it might seem surprising to encounter the exact same name in a different family tree, the repetition of names for completely different individuals is a known pattern in this era. A similar example is the name Enoch, which also belongs to multiple distinct figures across the varying ancestral lines [ברכת אשר על התורה, קאסוטו].
