Verse explainer
"Sons of God" marrying "daughters of men" sounds supernatural — but the oldest reading is a human story about a holy line abandoning its call.
That the sons of God saw the daughters of men that they were fair; and they took them wives of all which they chose.
BSBthe sons of God saw that the daughters of men were beautiful, and they took as wives whomever they chose.
The plain meaning
The flood narrative in Genesis 6 opens with a catastrophic blurring of boundaries. The phrase "sons of God" has generated three main readings across history: angels or divine beings, the line of godly Seth, or royal/ruling-class men. John Gill and most Reformation-era commentators land firmly on the Sethite reading: the descendants of Seth (the line that, from the days of Enos in Genesis 4:26, had been publicly identified with the worship of God) began crossing into the Cainite community, drawn purely by physical beauty. The phrase "all which they chose" is the tell — it signals unchecked appetite, not covenant discernment. The result was not a biological catastrophe but a moral one: the last boundary between devoted and corrupt humanity dissolved. The wickedness that follows in verses 5–6, grieving God to the heart, is the direct consequence of this indiscriminate mixing.
The common misreading
What the commentators say
Gill firmly rejects the angel interpretation — incorporeal beings cannot marry or generate offspring. He identifies the sons of God as Seth's posterity, who had been called by God's name since Genesis 4:26, living separate from the Cainites on higher ground. When they descended and chose wives solely on the basis of physical beauty, without regard to godly character or parental counsel, the last moral boundary collapsed — setting the stage for the universal corruption described in verses 5–6.
Henry reads the passage as a solemn warning about religiously mixed marriages driven by physical attraction. The sons of God — professors of true religion — should have sought partners who shared their devotion, but they let their eyes govern their hearts. The phrase 'all which they chose' marks the abandonment of godly counsel in favor of unchecked desire, and Henry sees this as the root cause of the corruption God surveys in the very next verses.
Barnes acknowledges the angel interpretation has ancient support but finds it untenable on contextual and theological grounds. He favors the Sethite view: the contrast between 'sons of God' and 'daughters of men' mirrors the earlier contrast between the two lines in chapters 4 and 5. The sin is not the act of marriage itself but the motive — beauty alone, chosen without regard to the covenant community — making the verse a diagnosis of spiritual decline rather than a supernatural episode.
The word behind it
"Sons of God." The identical phrase appears in Job 1:6 of heavenly beings, giving rise to the angel reading. But in Genesis the surrounding narrative concerns two human lineages, Seth's and Cain's. Gesenius notes the construct phrase can mark covenant relationship or divine calling, not only ontological nature. The contrast with 'daughters of men' (bənôt hāʾādām) reinforces a human distinction: a line set apart by devotion versus the broader human population outside that calling.
