Matthew Henry
From his Commentary on the Whole Bible. Henry comments on passages, not single verses — this entry covers Genesis 20:8–13. His four-level outline is real structure in the source text, so it is rendered as structure.
Abimelech, being thus warned of God in a dream, takes the warning, and, as one truly afraid of sin and its consequences, he rises early to obey the directions given him.
I.He has a caution for his servants, Gen 20:8.
Abraham himself could not be more careful than he was to command his household in this matter. Note, Those whom God has convinced of sin and danger ought to tell others what God has done for their souls, that they also may be awakened and brought to a like holy fear.
II.He has a chiding for Abraham. Observe,
1.The serious reproof which Abimelech gave to Abraham, Gen 20:9, Gen 20:10. His reasoning with Abraham upon this occasion was very strong, and yet very mild. Nothing could be said better; he does not reproach him, nor insult over him, does not say, "Is this your profession? I see, though you will not swear, you will lie. If these be prophets, I will beg to be freed from the sight of them:" but he fairly represents the injury Abraham had done him, and calmly signifies his resentment of it.
(1.)He calls that sin which he now found he had been in danger of a great sin. Note, Even the light of nature teaches men that the sin of adultery is a very great sin: be it observed, to the shame of many who call themselves Christians, and yet make a light matter of it.
(2.)He looks upon it that both himself and his kingdom would have been exposed to the wrath of God if he had been guilty of this sin, though ignorantly. Note, The sins of kings often prove the plagues of kingdoms; rulers should therefore, for their people's sake, dread sin.
(3.)He charges Abraham with doing that which was not justifiable, in disowning his marriage. This he speaks of justly, and yet tenderly; he does not call him a liar and cheat, but tells him he had done deeds that ought not to be done. Note, Equivocation and dissimulation, however they may be palliated, are very bad things, and by no means to be admitted in any case.
(4.)He takes it as a very great injury to himself and his family that Abraham had thus exposed them to sin: "What have I offended thee? If I had been thy worst enemy, thou couldst not have done me a worse turn, nor taken a more effectual course to be revenged on me." Note, We ought to reckon that those do us the greatest unkindness in the world that any way tempt us or expose us to sin, though they may pretend friendship, and offer that which is grateful enough to corrupt nature.
(5.)He challenges him to assign a cause for his suspecting them as a dangerous people for an honest man to live among: "What sawest thou, that thou hast done this thing? Gen 20:10. What reason hadst thou to think that if we had known her to be thy wife thou wouldst have been exposed to any danger by it?" Note, A suspicion of our goodness is justly reckoned a greater affront than a slight upon our greatness.
2.The poor excuse that Abraham made for himself.
(1.)He pleaded the bad opinion he had of the place, Gen 20:11. He thought within himself (though he could not give any good reason for his thinking so), "Surely the fear of God is not in this place, and then they will slay me." [1.] Little good is to be expected where no fear of God is. See Psa 36:1. [2.] There are many places and persons that have more of the fear of God in them than we think they have: perhaps they are not called by our dividing name, they do not wear our badges, they do not tie themselves to that which we have an opinion of; and therefore we conclude they have not the fear of God in their hearts, which is very injurious both of Christ and Christians, and makes us obnoxious to God's judgment, Mat 7:1. [3.] Uncharitableness and censoriousness are sins that are the cause of many other sins. When men have once persuaded themselves concerning such and such that they have not the fear of God, they think this will justify them in the most unjust and unchristian practices towards them. Men would not do ill if they did not first think ill.
(2.)He excused it from the guilt of a downright lie by making it out that, in a sense, she was his sister, Gen 20:12. Some think she was own sister to Lot, who is called his brother Lot (Gen 14:16), though he was his nephew; so Sarah is called his sister. But those to whom he said, She is my sister, understood that she was so his sister as not to be capable of being his wife; so that it was an equivocation, with an intent to deceive.
(3.)He clears himself from the imputation of an affront designed to Abimelech in it by alleging that it had been his practice before, according to an agreement between him and his wife, when they first became sojourners (Gen 20:13): "When God caused me to wander from my father's house, then we settled this matter." Note,
[1.]God is to be acknowledged in all our wanderings.
[2.]Those that travel abroad, and converse much with strangers, as they have need of the wisdom of the serpent, so it is requisite that that wisdom be ever tempered with the innocence of the dove. It may, for aught I know, be suggested that God denied to Abraham to punish them for this sinful compact if they will not own their marriage, why should God own it? But we may suppose that, after this reproof which Abimelech gave them, they agreed never to do so again, and then presently we read (Gen 21:1, Gen 21:2) that Sarah conceived.

Then, from a wish to make excuses for himself, he said, “Don’t think I lied to you in that way; ‘She is my sister on my father’s side, though not my mothers, and she became my wife all the same.’ She claims the same father as I … and hence I called her my sister. So don’t condemn me. Even if the fear of death brought me to this sorry pass and the dread of your killing me but sparing her, still what was said by me was not a lie in the way you imply.” See what great pains the good man takes to show that he had not told a lie even in this matter. For you to learn everything precisely from me (he is saying), listen also to the plan we formed between us “when God led me out from my father’s home.” Observe in this case, I ask you, the good man’s wisdom. He teaches them by way of story that from the very beginning he had a special relationship with God and that God had personally moved him from home and led him there so that the king might learn that he was one of those people who had great confidence in God.
(Chapter 20, verse 12.) Truly my sister is from my father, but not from my mother. That is, her father is Aran, not her mother. But because it says in Hebrew: truly my sister is the daughter of my father, and not the daughter of my mother: and it sounds more likely that she should be called Abraham's sister, we say this in her defense, that at that time such marriages were not yet prohibited by law.

Summary
Genesis 20:12 records Abraham's carefully crafted, yet dangerously deceptive, explanation to King Abimelech regarding Sarah's identity. Abraham clarifies that Sarah is indeed his paternal half-sister, sharing the same father but a different mother, and simultaneously affirming her status as his wife. This statement, while technically factual, functioned as a perilous half-truth, strategically employed by Abraham out of fear for his life, but which ultimately imperiled Sarah's purity and Abimelech's innocence, powerfully illustrating the complex and often perilous nature of human deception even among God's chosen.
Context
Literary Context
Genesis 20:12 is situated within a recurring narrative pattern in Abraham's life, echoing a similar incident in Genesis 12:10-20. This chapter immediately follows the dramatic destruction of Sodom and Gomorrah in Genesis 19, and Abraham's intercession for them. As Abraham journeys southward to Gerar, he once again resorts to presenting Sarah as his sister, driven by a fear that the local inhabitants, whom he perceives as lacking the fear of God, would kill him to take his beautiful wife (Genesis 20:11). God's direct and miraculous intervention, through a dream warning to King Abimelech, prevents the king from unknowingly committing a grave sin, thereby protecting Sarah and the integrity of the covenant lineage (Genesis 20:3-7). When confronted by Abimelech, Abraham offers the explanation found in Genesis 20:12 as his justification, revealing the factual, albeit incomplete, nature of his initial claim.
Historical & Cultural Context
In the ancient Near East, the concept of "sister" could sometimes be used more broadly to denote a close female relative or even a beloved wife, but Abraham's precise clarification in this verse ("daughter of my father, but not the daughter of my mother") explicitly defines Sarah as his paternal half-sister. Marriage between paternal half-siblings was not uncommon and was considered permissible in early patriarchal society, as evidenced by this very account and other ancient legal codes. This practice contrasts sharply with later Mosaic Law, which explicitly prohibited such unions as a form of incest, reflecting a progressive development in God's moral standards for His covenant people (Leviticus 18:9). Abraham's fear of being killed for his wife was also a real concern in a world where powerful rulers could seize women for their harems, and eliminating a husband was a common means to achieve this. The narrative thus provides a window into the social customs, legal norms, and inherent dangers of the patriarchal period.
Key Themes
This verse contributes significantly to several overarching themes within Genesis and the broader biblical narrative. Firstly, it highlights the theme of human fallibility and divine faithfulness. Despite Abraham's status as the patriarch of faith, his repeated resort to deception underscores his human weakness and lack of trust in God's protection, even after numerous divine promises. Yet, God's unwavering faithfulness is powerfully demonstrated through His direct intervention to protect Sarah and His covenant promises, preventing Abimelech's unwitting sin (Genesis 20:6-7). Secondly, the narrative deepens the theme of God's sovereignty over human action. Even when His chosen servant falters, God remains in control, supernaturally orchestrating events to fulfill His purposes and preserve the messianic lineage. Finally, it explores the theme of the nature of deception, illustrating that "half-truths" are a form of dishonesty that can lead to severe consequences and undermine trust, demonstrating that partial honesty can be as damaging as an outright lie (Proverbs 29:25).
Exposition and Analysis
Key Word Analysis
This adverb emphasizes the truthfulness of Abraham's subsequent statement. It conveys a sense of confirmation or affirmation, as if to say, "It is truly so." In this context, it highlights the factual accuracy of Sarah being his half-sister, which Abraham uses to lend credibility to his partial disclosure.
Derived from a root meaning "brother," this term, while primarily meaning a female sibling, can be used broadly in Hebrew to denote a close female relative or even a kinswoman. However, Abraham immediately qualifies it, making it clear he means a biological half-sister. Its use here is central to Abraham's deceptive strategy, as it presents a true relationship while concealing a more pertinent one.
This word designates a female, specifically a married woman. Its inclusion at the end of Abraham's explanation is crucial, as it is the very truth he initially withheld. The fact that she "became my wife" indicates a legally recognized marital union, making his prior omission a deliberate deception.
Verse Breakdown
"And yet indeed she is my sister"
This initial clause serves as Abraham's primary defense and justification. The "indeed" (H546, ʼomnâh) emphasizes the factual accuracy of Sarah being his sister, setting the stage for his partial revelation. It's the "truth" he wants Abimelech to focus on, legitimizing his initial claim.
"she is the daughter of my father, but not the daughter of my mother"
This phrase provides the precise genealogical clarification, defining the nature of their sibling relationship. It specifies that Sarah is Abraham's paternal half-sister, sharing the same father (Terah) but having a different mother. This detail was crucial in ancient societies to distinguish types of sibling relationships and their implications for marriage.
"and she became my wife"
This final, critical clause reveals the complete truth that Abraham initially concealed. It acknowledges their marital status, which was the essential piece of information that would have prevented the entire crisis. The phrase "became my wife" implies a formal, recognized union, highlighting the deliberate nature of Abraham's prior omission.
Literary Devices
Genesis 20:12, within its broader narrative, employs several significant literary devices. Situational Irony is prominent, as Abraham, a man chosen by God and called to be a blessing, repeatedly resorts to a deceptive "half-truth" out of fear, placing his wife and the covenant lineage in jeopardy. The irony deepens when the "pagan" king Abimelech demonstrates greater moral integrity and fear of God than the patriarch himself, highlighting Abraham's human frailty. The narrative also utilizes Foreshadowing, as the permissibility of half-sibling marriage in Abraham's time implicitly points towards the later, stricter prohibitions found in the Mosaic Law (Leviticus 18:9), illustrating the concept of Progressive Revelation in God's moral standards. Finally, the entire incident serves as a Moral Parable or Cautionary Tale, demonstrating the perilous consequences of Deception, even when cloaked in partial truth, and underscoring the importance of complete honesty and unwavering trust in divine providence.
Theological and Thematic Connections
Genesis 20:12, while a statement of fact, is embedded in a narrative that powerfully underscores God's unwavering faithfulness despite human frailty. Abraham, the recipient of magnificent covenant promises, repeatedly succumbs to fear and resorts to deception, jeopardizing the very lineage through which the Messiah would come. Yet, God sovereignly intervenes, not only protecting Sarah from defilement but also preserving Abimelech from sin, demonstrating that His purposes will prevail regardless of human failure. This incident highlights that God's covenant is secured by His character, not by the perfection of His human partners, offering profound comfort and a reminder of divine grace.
Reflection and Application
Genesis 20:12, and the broader narrative it belongs to, offers profound and challenging lessons for believers today. It starkly reminds us that even individuals of profound faith, chosen by God and privy to His promises, are susceptible to fear, self-preservation, and the temptation of deception. Abraham's resort to a half-truth, though technically factual, created a dangerous situation and nearly led to grave sin, underscoring that partial honesty can be as damaging as an outright lie. This calls us to a radical commitment to integrity and truthfulness in all our dealings, recognizing that our ultimate security lies not in our clever schemes but in God's unfailing providence. Furthermore, the passage provides immense comfort and encouragement: even in our moments of fear and failure, God remains utterly faithful to His promises. He supernaturally intervenes to protect His purposes and His people, demonstrating that His grace extends beyond our weaknesses. This should compel us to cultivate a deeper trust in Him, choosing courageous obedience over deceptive self-reliance, knowing that He is fully capable of protecting us and fulfilling His plans, even when we falter.
Questions for Reflection
FAQ
Was Abraham lying when he said Sarah was his sister?
Abraham's statement was a dangerous half-truth rather than a complete fabrication. Sarah was indeed his paternal half-sister, sharing the same father (Terah) but a different mother. However, he deliberately omitted the crucial fact that she was also his wife, which constituted a deception intended to protect himself. This withholding of vital information, leading others to a false conclusion and nearly causing Abimelech to commit a grave sin, is considered a form of deception. The Bible consistently portrays truthfulness as a virtue and deception, even partial, as a moral failing.
Why was marriage between half-siblings allowed in Abraham's time but later prohibited in the Mosaic Law?
The Bible reveals a principle of progressive revelation, where God's moral and ceremonial laws are revealed incrementally over time, guiding humanity towards a deeper understanding of His holiness and design. In the early patriarchal period, certain practices, including marriage between paternal half-siblings, were permissible within the prevailing societal norms and before the full establishment of God's covenant community, Israel. However, as God established the nation of Israel and gave the Mosaic Law, He instituted stricter regulations regarding kinship and marriage, as seen in Leviticus 18:9 and Deuteronomy 27:22. These prohibitions were part of God's design to set Israel apart as a holy nation, distinguishing them from the surrounding cultures and promoting a higher standard of purity and order within the covenant community.
Does Abraham's deception diminish his status as a man of faith?
While Abraham's actions in Gerar (and previously in Egypt, Genesis 12) reveal a significant lapse in faith and reliance on God's protection, they do not ultimately diminish his status as a man of faith. The Bible honestly portrays the struggles and failures of its heroes, demonstrating that even great figures of faith are fallible humans. Abraham's faith was not perfect, but it was real and ultimately enduring, as affirmed in Hebrews 11:8-10. This narrative highlights God's grace and His ability to work through imperfect individuals to fulfill His divine purposes, demonstrating that God's faithfulness to His covenant is not contingent on human perfection but on His own steadfast character (2 Timothy 2:13).
Christ-Centered Fulfillment
Genesis 20:12, though detailing Abraham's human failing, powerfully illustrates God's unwavering faithfulness, which ultimately points to Christ. Abraham's deception threatened the purity of the messianic lineage, as Sarah was the promised mother through whom Isaac, and eventually Christ, would come. God's direct and miraculous intervention to protect Sarah from defilement, even when Abraham faltered, underscores His meticulous preservation of the line of promise. This divine faithfulness, overcoming human sin and weakness, foreshadows the ultimate faithfulness of God in sending His Son, Jesus Christ. Unlike Abraham, who faltered in fear and resorted to a half-truth, Jesus lived a life of perfect obedience and complete truth, never compromising His integrity or relying on human schemes. He is the true and perfect Seed of Abraham through whom all nations are blessed (Galatians 3:8). Christ's perfect life, atoning death, and resurrection ensure the fulfillment of all God's promises, providing a salvation that is not dependent on human faithfulness but on God's perfect plan and the unfailing work of His Son. Thus, this narrative, even in its depiction of human weakness, magnifies the steadfast character of God, who in Christ, perfectly secured the covenant and provided the ultimate answer to humanity's sin and fear.
