Rephaim
Short answer: The Rephaim were an ancient people group known in the Old Testament for unusual height and for living in the regions east of the Jordan before Israel entered the land. 2 Samuel 21:15-22 belongs to a cluster of stories in which David and his servants fight Philistine warriors described as descendants of the giants. The passage does not present these figures as demons, as spirits of the dead, or as a surviving rival kingdom. It presents them as real opponents in real battles who are killed one by one: Ishbi-benob, Saph, and the man with twelve fingers and twelve toes, plus Goliath the Gittite in the parallel account. The weight of the passage falls on the servants who strike them down and on the notice that they were subdued, not on speculation about what the Rephaim were.
Who the Rephaim were in the Old Testament
The word Rephaim appears in the Hebrew Bible in more than one sense. In many passages it names an ancient people, sometimes called the Rephaim, sometimes associated with the Zuzim and the Emim. Genesis 14:5-6 places them in the narrative of Chedorlaomer's campaign: "In the fourteenth year Chedorlaomer came, and the kings who were with him, and struck the Rephaim in Ashteroth Karnaim, the Zuzim in Ham, the Emim in Shaveh Kiriathaim," (Genesis 14:5-6). They are listed among the peoples already living in the land before Abraham's descendants arrived.
That single mention is enough to establish that the Rephaim were a historical population, not a mythical race invented for storytelling. They occupy real geography. Ashteroth Karnaim and Shaveh Kiriathaim are places, not symbols. The Rephaim belonged to the same broad category as other pre-Israelite peoples the Old Testament remembers as tall and formidable, and the biblical writers treat them as having been defeated long before Israel's own conflicts with them.
What the Bible does not give is an origin story. It never says where the Rephaim came from, when they began, or how many there were. The Old Testament simply assumes its readers know of them as an old, tall people whose memory lingered in the land. That silence is worth noticing, because readers who want a tidy taxonomy of ancient giants will not find one here. The text gives enough to identify them and enough to know they were beaten, which is exactly the amount of information the narrative requires.
The Rephaim and the Anakim: overlapping memories of tall peoples
Deuteronomy connects the Rephaim to the Anakim, another people remembered for height. Concerning the land east of the Jordan, the text says, "(The Emim lived there before, a great and numerous people, and tall as the Anakim." (Deuteronomy 2:10-11). The parenthetical remark tells us the Emim were comparable to the Anakim in stature, and the surrounding verses identify the Emim with the Rephaim by another name. The Old Testament often describes a conquered people by more than one label depending on the region or the era.
Og king of Bashan is the last named survivor of the group. Deuteronomy 3:11 says, "(For only Og king of Bashan remained of the remnant of the Rephaim. Behold, his bedstead was a bedstead of iron. Isn't it in Rabbah of the children of Ammon? Nine cubits was its length, and four cubits its width, after the cubit of a man.)" The detail about the iron bedstead is the storyteller's way of making the size credible and memorable. It also marks an endpoint: after Og, the Rephaim are described as a remnant, not a nation.
That last point matters for reading 2 Samuel 21. If Og was the last remnant of the Rephaim in Bashan, then the Philistine giants of David's day are not a revival of Rephaim kingship. They are the same stock remembered under a different description: men of unusual size among Israel's enemies. The Bible is comfortable using older language to describe later realities, and readers should be too.
What happens in 2 Samuel 21:15-22
The passage opens with David in battle. "The Philistines had war again with Israel; and David went down, and his servants with him, and fought against the Philistines. David grew faint;" (2 Samuel 21:15). The narrative is direct and unadorned. There is no demonic confrontation, no curse, no ritual. There is a king who has grown old and tired, and there are enemies who keep coming.
Four Philistine warriors are named or described, and each is killed by one of David's men rather than by David himself. Abishai strikes down Ishbi-benob, who is described as one of the descendants of the giant and whose spear weighed three hundred shekels of bronze. Sibbecai the Hushathite kills Saph. Elhanan son of Jair kills the brother of Goliath the Gittite. The fourth is the man with six fingers on each hand and six toes on each foot, killed by Jonathan son of Shimei, David's brother. The sequence ends with the summary that they fell by the hand of David and by the hand of his servants.
The Chronicler parallels the same material. 1 Chronicles 20:4-8 records Sibbecai killing Sippai and then adds the man of great stature, noting that these were born to the giant in Gath and fell by the hand of David and his servants. The two accounts agree in substance: a small set of Philistine fighting men of exceptional size is eliminated, and the victories are credited to David's servants as much as to David.
Why the passage lists the battles instead of dramatizing them
Modern readers often expect a giant story to be tense. The David and Goliath narrative in 1 Samuel 17 is tense, because there the whole army is afraid and one young man stands alone. 2 Samuel 21 is not written that way. The giants fall in a series of short notices, almost like battle reports. The reader is told who fought, who died, and who killed them, and then the passage moves on. The restraint is deliberate.
The effect is to demystify the giants. By the time Israel is established under David, men of extraordinary size are no longer an existential threat to the nation. They are a recurring military problem handled by competent soldiers. The narrative gives them no aura and no speeches. They are strong, they are dangerous, and they lose. That is the point the writer is making about the state of the kingdom.
There is also a pastoral edge to the arrangement. David, the hero of Goliath, is now the aging king who grows faint and must be protected by his men. The same chapter that records the killing of giants also records that David's servants swore he would no longer go out to battle with them, so that the lamp of Israel would not be put out. The giants are defeated, and the king who once defeated one is cared for. Both facts stand together without embarrassment.
David growing faint and the shift to his mighty men
The opening verse gives a detail that preachers sometimes pass over too quickly. David grew faint. The Hebrew suggests exhaustion, the plain weariness of an older man in armor. The next verse records that Ishbi-benob intended to kill him, and Abishai intervened. The narrative does not treat this as a moral failure. It treats it as a fact of age and a reason for the change in how Israel's wars are fought.
This connects naturally to the wider material about David's mighty men. The lists in 1 Chronicles 11 and 1 Chronicles 12 celebrate the warriors who gathered to David and carried his campaigns. The men who kill the Philistine giants in 2 Samuel 21 belong to that same company: Abishai, Sibbecai, Elhanan, Jonathan. The kingdom is not sustained by one extraordinary individual but by a body of trained, loyal soldiers. The giant-killers are named because the writer wants them remembered.
The theological shape here is worth stating plainly. God's deliverance of Israel in this period runs through ordinary men doing their duty. The Bible does not frame the defeat of the giants as a miracle that suspends normal combat. It frames it as warfare, with named participants and specific outcomes. The glory belongs to God, but the means are the servants he provided.
The Rephaim and the dead in Isaiah and the Psalms
The word Rephaim also appears in the Old Testament in a different sense, referring to the dead or to those in the grave. Isaiah 26:14 says, "The dead shall not live. The departed spirits shall not rise. Therefore you have visited and destroyed them, and caused all memory of them to perish." Here the term functions as a poetic designation for the dead, the shadowy population of Sheol. It is not describing the ancient tall people of Bashan.
This double usage is the main reason the topic is confusing. The same consonants can name a historical people and can name the dead. Context decides, and in most cases the context is clear. When the text names a place, a king, or a battle, it means the people. When it speaks of those who do not rise and whose memory perishes, it means the dead. Reading one sense into the other produces errors.
Isaiah's use is actually a contrast with God's own people. The nations and their dead will not rise, but Israel is told that their dead shall live and their bodies shall rise. The verse is not a statement about giants at all. It is a statement about the difference between those whom God remembers and those whose memory he causes to perish. Treating it as a proof text about ancient races misreads both the word and the argument.
What 2 Samuel 21:15-22 does not say
The passage does not say the Rephaim were demons, fallen angels, or a hybrid race. Those ideas come from outside the text and are imported into it. The Hebrew Bible consistently treats the Rephaim, the Emim, the Zuzim, and the Anakim as human populations, however tall or imposing. They eat, fight, marry, and die as people do. Nothing in the passage suggests otherwise.
The passage does not say the giants were invincible, nor does it present David as their sole conqueror. Four Philistines fall, and three of them are killed by men other than David. The summary at the end credits the victories to David and his servants together. Any reading that turns this into a solo hero story has to ignore the names the writer took care to include.
The passage also does not say that the Philistine giants were literally Rephaim in the strict genealogical sense that Og was. The Hebrew phrases used in 2 Samuel 21 and 1 Chronicles 20 identify them as descendants of the giant, a description that links them to the old tradition without making them a surviving clan of Bashanite kings. The connection is one of kind and reputation, not of a continuous royal line. The narrative is content to let that stand without further explanation.
Biblical fidelity check
What the passage establishes is straightforward. David and his servants fought Philistines. Some of those Philistines were of exceptional size. David's servants killed them. David had grown faint and was kept from battle thereafter. The writer records these events in plain prose with names, places, and outcomes. Nothing in the passage depends on speculative reconstruction, and nothing in it requires reading later theological categories back into the text.
A common misreading takes the word Rephaim to mean the spirits of the dead and then reads the giants of 2 Samuel 21 as those spirits appearing in human form. That is wrong on two counts. First, the immediate context names real opponents with real weapons fighting real battles in real places such as Gob and Gath. Second, the Old Testament's use of Rephaim for the dead is a separate poetic usage, as in Isaiah 26:14, where the point is that the dead do not rise. The historical and the poetic senses must be kept apart.
Other passages that speak to 2 Samuel 21:15-22
The wider story of David's rise and the men around him is told across several chapters. 1 Chronicles 10: Saul's Death and the Kingdom Given to David sets the stage for David's reign and explains why the conflict with the Philistines mattered so much. 1 Chronicles 11: David Anointed King and His Mighty Men introduces the warriors who would later face the giants. 1 Chronicles 12: David's Mighty Men and the United Kingdom shows how those fighters gathered to him from across Israel. And 1 Chronicles 1: Adam to Edom's Chiefs traces the genealogies of the peoples of the land, including the old populations remembered alongside the Rephaim.
Frequently asked questions
Were the Rephaim giants or demons?
The Old Testament treats the Rephaim as a human people known for unusual height, living in regions east of the Jordan before Israel arrived. Deuteronomy 3:11 calls Og the last of the remnant of the Rephaim and describes his iron bedstead. The Philistine opponents in 2 Samuel 21 are likewise described as descendants of the giant and are killed in ordinary combat. Nothing in the text identifies them as demons or as spirits. The idea that they were demonic comes from outside Scripture and should not be read back into these passages.
Why does the word Rephaim sometimes mean the dead?
Hebrew uses the same consonants for the ancient people and for the departed. Context decides which is meant. When a passage names a place, a king, or a battle, it refers to the people, as in Genesis 14:5-6. When it speaks of those who do not rise, as in Isaiah 26:14, it refers to the dead in Sheol. These are distinct usages, and confusing them produces doctrinal errors the text itself does not support. Careful reading of the surrounding verses resolves the ambiguity in nearly every case.
How many giants did David and his men kill in 2 Samuel 21?
The passage describes four Philistine warriors of exceptional size. Abishai killed Ishbi-benob, Sibbecai killed Saph, Elhanan killed the brother of Goliath the Gittite, and Jonathan son of Shimei killed the man with six fingers on each hand and six toes on each foot. The parallel in 1 Chronicles 20:4-8 names Sippai and the man of great stature. The count varies slightly between accounts because of naming differences, but both agree that a small number of Philistine giants fell to David and his servants, and that the Philistines were subdued.
