Nephilim: Giants and the Borders Between Gods and Humans
From the series The Bible Is Not Literal, published by Memra.

Four verses, and the ground of the narrative seems to give way. Before the flood, while Genesis is still describing humanity's multiplication over the earth, a short, harsh scene appears: daughters are born, "sons of God" see them, take wives for themselves, God speaks of a limit, and then the Nephilim appear. The text does not slow down to explain who these figures are, nor does it trouble itself to satisfy the reader's curiosity. The strangeness is part of the episode's force.
This is why Genesis 6:1–4 tends to attract so much sensationalism. The passage seems to offer raw material for unbridled speculation: giants, hybrid beings, a lost race, visitors from another world. But read closely, it works in a different key. Its energy lies less in describing an extraordinary biology than in showing a world in which boundaries are being violated and human greatness already appears entangled with disorder and judgment. When Numbers 13 picks up the word "Nephilim" again, the effect shifts once more: we are no longer facing an ancient memory on the threshold of the flood, but a fear-driven report that turns enemies into nightmares.
Before The Flood: A Gaze That Takes
The movement of Genesis 6 is quick, but not careless. The first verse opens with something common, even promising: humanity multiplies on the face of the earth, and daughters are born. The scene begins in the register of fertility, of life's expansion. There is nothing monstrous in this yet. What follows disfigures the picture.
The "sons of God" see that the daughters of men were beautiful. Then, "they took as wives whomever they chose." The verbs deserve attention. First, seeing; then, taking. The text describes no covenant, no conversation, no mutual choice, no celebrated marriage. The center of the action lies with the one who looks and appropriates. The women enter the sentence as the object of another's desire and act. What should have been an encounter appears instead as capture.
This small sequence matters because it sets the moral tone of the passage. Whatever the exact identity of the "sons of God," the text shows them acting without measure. The detail "whomever they chose" intensifies this: it is not a matter of a particular bond, but of a selection governed by appetite and power. The verb "take" carries more weight than any attempt to romanticize the scene.
The contrast between the two named groups also stands out. On one side, "sons of God"; on the other, "daughters of men." The narrative does not pause to explain the expression, and this reticence is significant. The reader senses an asymmetry, a crossing of orders, but is given no detailed map. The effect is deliberate: the episode is built around a boundary being crossed.
The Verse That Cuts Through The Scene
In the middle of this condensed action, God speaks. Verse 3 interrupts the sequence and introduces a limit: human life will not extend indefinitely; its days will be a hundred and twenty years. The passage does not fully clarify the contours of this word. Readers debate whether it refers to the maximum span of a human life or to a countdown before the coming judgment. The text alone does not eliminate the doubt entirely. But one thing is clear: the scene of appropriation and mixing is not narrated as triumph. It provokes a divine response.
This cut is decisive for reading the whole episode. Genesis 6:1–4 is not interested in exalting extraordinary beings. It is set within the preparation for the flood. Right afterward, the chapter opens onto a broader diagnosis of human wickedness. These four verses, then, do not function as a curious file on an extraordinary lost race. They function as a symptom of a world in disorder, where the creature's proper measure is being abandoned.
The divine speech puts mortality back at the center. When the narrative touches this point, it dismantles any naive fascination with greatness. The human being remains flesh, finite, subject to limit. If there was here a pretension to exceed the human condition, the text surrounds it with judgment, not admiration.
There Were Nephilim On The Earth
Then comes the most famous and most fog-bound phrase: "The Nephilim were on the earth in those days, and also afterward." The construction is frustrating for anyone seeking a clean classification. The Nephilim enter almost sideways, as a passing remark, and the verse does not say unambiguously everything we might wish to know. Are they the result of the union just mentioned? Were they already there before? The phrase "and also afterward" extends their presence but does not organize a precise chronology.
This ambiguity deserves respect. The verse places the Nephilim near the scene of the "sons of God" and the "daughters of men," but offers no detailed genealogy. The text suggests connection; it does not hand over a dossier. The temptation to fill the silence with certainty usually reveals more about the reader's imagination than about the passage.
The end of the verse adds another layer: "these were the mighty men who were of old, men of renown." Here the surprise is that the Nephilim — or at least the figures associated with this scene — are not described merely as frightening beings. They are mighty ones, men of renown, figures of ancient fame. The semantic field is that of strength and celebrity.
This changes the reading considerably. The text is not simply sketching monsters out of folk tale. It is evoking grand, memorable figures, belonging to the imagination of extraordinary deeds. But this memory is glued to the announcement of limit and to the context preceding the flood. Fame, here, absolves no one. On the contrary: it may be a sign of a world that has learned to admire the wrong kind of greatness.
This detail matters both for a Christian reading and for a critical reading of power. There are forms of greatness that seduce precisely because they impress, dominate, and leave a name. Genesis 6 does not separate that brilliance from the moral problem; it places both in the same frame.
The Text Does Not Hand Over A Map
At this point, caution becomes an obligation. The episode affirms the existence of Nephilim "in those days" and associates them with a scene of transgression and ancient fame. It does not, however, define with modern precision what these beings were. The identity of the "sons of God" also remains open within the passage itself.
This is why different readings have arisen over time. Some understand the text as speaking of heavenly beings; others prefer to see it as a description of powerful men, perhaps rulers or warriors acting violently; others still try to fit it into a dispute between human lineages. The problem is not that diverse interpretations exist. The problem begins when one of them is treated as though it were explicitly written in the verse, when the verse does not formulate it that way.
The word "Nephilim" itself does not settle everything either. Translating it as "giants" may convey part of the impact that tradition has attached to the term, especially in Numbers 13, but in Genesis 6 the text does not measure height, does not describe anatomy, does not offer bodily traits. It suggests exceptionality; it does not draft a medical report.
This has consequences for any attempt to use the Bible as proof of a hybrid population of giants. Nothing in Genesis 6:1–4 allows one to demonstrate, in historical or scientific terms, the existence of an identifiable species of this kind. Archaeology and the life sciences require another kind of evidence: controlled excavation, verifiable analysis, rigorous documentation. These four verses do not supply that, and the available material does not authorize that leap.
Nor does the text support the extraterrestrial hypothesis. That idea may seem seductive to a modern imagination accustomed to turning ancient riddles into cosmic fiction, but it does not arise from the passage. It is a reading projected onto the text, not demanded by it.
Reading responsibly, here, means accepting that the Bible sometimes preserves zones of shadow. Not every obscurity is an invitation to delirium; often it is part of how the text produces its meaning.
In The Promised Land, Fear Magnifies The Enemy
When the word reappears in Numbers 13:33, the setting is different. We are no longer in the antediluvian world, but on the edge of the land of Canaan, in the account of the spies. And that changes everything. There, the mention of the Nephilim does not come as the narrator's comment on ancient times; it arises in the speech of frightened men.
The sentence is revealing: "There we saw the Nephilim (the sons of Anak, who come from the Nephilim), and we seemed to ourselves like grasshoppers, and so we seemed to them." The emotional center of the verse lies less in the Anakim than in the spies' self-perception. "To ourselves" comes first. Before knowing how they were seen by the other, they already see themselves diminished.
This order matters. Fear produces an optic. The spies interpret reality from their own smallness and then project that image onto the enemy: "so we seemed to them." There is no objective measurement of the adversary here. There is the language of a community that feels defeated before the battle.
This is where Numbers helps us read Genesis without fantasy. The word "Nephilim" in 13:33 does not function as an independent biological report. It functions as rhetorical amplification. The name summons an imagination of disproportion and extreme threat. To say "we saw the Nephilim" is to turn the challenge into impossibility.
The very contrast with "grasshoppers" sharpens this. The problem is not only that the enemy is large; it is that the spies narrate themselves as minuscule. Fear shrinks the speaker and magnifies what stands before him. The passage shows how a people can be disarmed by the way it describes its obstacles.
Thus the same term works differently in the two texts. In Genesis, it belongs to an ancient picture of broken limits and fame under judgment. In Numbers, it enters the rhetoric of panic. Joining the two passages as if they formed a single report on giants is to lose precisely what each one does in its own context.
Between Fascination And Panic
These two scenes, placed side by side, reveal a persistent human trait. On one side, fascination with greatness without measure — with strength, with fame, with the exception that seems to lift some above the ordinary. On the other, the panic that turns adversaries into near-mythical creatures and reduces the self to the condition of an insect.
Genesis 6 dismantles the first temptation. The "men of renown" appear in a world heading toward judgment. Their brilliance does not correct the corruption of the scene. The passage refuses to treat extraordinary power as an automatic sign of blessing or nobility.
Numbers 13 exposes the second temptation. The terrible name given to the enemy does not merely describe the enemy; it describes the speaker. The community that absolutizes the obstacle loses, along with courage, an accurate view of reality.
This double warning is more useful than any curiosity about legendary bones. Some religious readings turn the Nephilim into fuel for apocalyptic fear, occult theories, or a cult of the extraordinary. The biblical text moves in another direction. It does not feed the imagination so that discernment might be abandoned; it provokes the imagination so that we might recognize where desire exceeds its limit and where fear distorts testimony.
How To Read Without Doing Violence To The Text
One concrete interpretive consequence follows. Genesis 6:1–4 should not be read as though it were a lost chapter of ancient biology. Its place is theological and narrative: it prepares the reader to understand the gravity of the pre-flood world. What we see there is disorder reaching the point of striking at the very boundaries that sustain creation.
Numbers 13:33, in turn, calls for a different kind of care. It is not a second proof of the existence of giants; it is part of an interested discourse, produced by spies overcome by fear. To use it as neutral testimony is to ignore the dramatic function of the speech within the chapter.
For Christian faith, this does not empty the text; on the contrary, it makes it more demanding. The question ceases to be "what secret creatures does the Bible mention?" and becomes "what form of greatness seduces us?" and "how does fear alter what we claim to see?" The episode becomes less useful for curiosity and more incisive for conscience.
The Bible, here, does not ask the reader to choose between credulity and skepticism before ancient legends. It asks something harder: to resist both the allure of transgressive force and the rhetoric that turns threat into inevitable destiny. Genesis 6 and Numbers 13, read together without being confused, speak of a world in which desire and fear can manufacture giants — some to be admired, others to be feared. In both cases, the result is a loss of measure.
If the text still lives, it is because we still know how to do this. We still call greatness what is born of appropriation. We still inflate the size of our enemies until we feel like grasshoppers. And we remain tempted to trade the patient reading of Scripture for spectacular explanations that spare us from facing that mirror.
