What is the meaning of Genesis 5:13?

And after he had become the father of Mahalalel

• Genesis 5:13 opens with Kenan’s pivotal moment of fatherhood, continuing the unbroken genealogical chain from Adam to Noah (Genesis 5:1–32) that Luke later traces all the way to Christ (Luke 3:37).

• Scripture highlights firstborn sons to mark covenant history, similar to Seth (Genesis 5:3) and Shem (Genesis 11:10).

• This phrase underscores God’s faithfulness to His command, “Be fruitful and multiply” (Genesis 1:28), and shows the family line through which the promise of Genesis 3:15 will ultimately be fulfilled.

Kenan lived 840 years

• These extraordinary pre-Flood lifespans—Adam 930, Seth 912, Enosh 905 (Genesis 5:5–11)—reflect a still-unaltered creation where environmental conditions and genetic vigor supported long life (Genesis 1:31; Genesis 9:29).

• The number is given as literal history, anchoring Kenan in real time and space, not myth.

• Long life allowed truth about God to be preserved and transmitted firsthand for centuries; for example, Adam was still alive during Lamech’s lifetime (compare Genesis 5:3–28).

• God later limits human life to “one hundred and twenty years” (Genesis 6:3) and Moses notes an average of seventy to eighty (Psalm 90:10), making Kenan’s 840 a clear marker of the antediluvian era.

And had other sons and daughters

• Scripture’s brief yet crucial note parallels Adam (Genesis 5:4) and Noah (Genesis 9:19), revealing that population growth came through multiple children in every generation.

• These unnamed sons and daughters demonstrate that every person bears God’s image (Genesis 1:27) and shares Adam’s lineage (Acts 17:26), emphasizing universal accountability and the spread of early human families.

• By recording “other” children, Genesis affirms both the literal historicity of early mankind and the inclusiveness of God’s blessing beyond the principal Messianic line.

summary

Genesis 5:13 records real history: Kenan fathers Mahalalel, lives 840 more years, and raises a sizable family. Each element affirms God’s ongoing blessing of fruitfulness, preserves the Messianic genealogy, and situates Kenan within a literal antediluvian world of extraordinary longevity.
