Genesis 5 is dominated by a linear, apparently unbroken genealogy that carries the promised line descendant by descendant from Adam to Noah.
The previous unit ended by shifting focus away from the seed of the serpent in Cain to the offspring of promise in Seth (4:26): “To Seth also a son was born, and he called his name Enosh. At that time people began to call upon the name of Yahweh.” This sets the stage for the linear genealogy of ch. 5, which only highlights how the Messianic hope was preserved from generation to generation.
- “Image and likeness” language is shown to point to “sonship”–Adam of God and Seth of Adam (Gen. 5:1–3; Luke 3:38).
- Little commentary is offered through the genealogy, suggesting that the point is to move us to Noah. Focus is brought to the 7th and 10th generations by the comment that “Enoch walked with God” (Gen. 5:22, 24), and in Lamech’s declaration at the birth of Noah (Gen. 5:29): “Out of the ground that Yahweh has cursed this one shall bring us relief from our work and from the painful toil of our hands.” The messianic hope, therefore, was passed on through the generations.
- The fact that every generation (except Enoch) died, stresses the permanent hold of the curse on humanity. God’s promise in Gen. 2:17 is proving true, and the weight of this curse is highlighted in Lamech’s final cry for relief (Gen. 5:29).
- The linear genealogy ends segmented, highlighting that Noah had three sons: Shem, Ham, and Japheth (Gen. 5:32). The arrangement highlights Shem, even though the genealogy in Genesis 10 suggests that Japheth may have been the oldest. The “youngest son” uncovered Noah’s nakedness (Gen. 9:24).
