Hebrew · 9 what the commentators say
Meaning in one sentence
Explore the Hebrew word 'metsachaq' and the debate over whether Ishmael was mocking or playing with Isaac, and why Sarah reacted so strongly.
Research Summary
- Meaning: Sarah saw Ishmael engaged in an action described by the participle metsachaq, likely mocking or playing in a way she perceived as contemptuous toward Isaac and the covenant.
- Key words: רָאָה (ra’ah, “saw”) and מְצַחֵק (metsachaq, Piel participle of צָחַק, “to laugh, mock, play”). The same root appears in Isaac’s name.
- Main debate: Whether Ishmael’s action was malicious mockery or innocent play that Sarah misread. The Hebrew allows both, and the context (v. 10 and Galatians 4:29) favors mockery.

Scholars' Consensus
Commentators agree on the basic scene: Sarah witnessed Ishmael engaged in some activity with or toward Isaac, and that activity prompted her to demand the expulsion of Hagar and her son. The word translated “mocking” is the Piel participle מְצַחֵק (metsachaq), from the root צָחַק (tsachaq, “to laugh”). That same root forms the name Isaac. The debate is about what kind of action the participle describes, and how severe it was. Calvin, Gill, and Matthew Henry read it as contemptuous mockery, an insult to God’s promise in the person of Isaac. The Cambridge Bible argues the verb is better rendered “playing” (as in the LXX and Vulgate, which supply an object: “with Isaac her son”), suggesting Sarah saw harmless play and reacted from jealousy. Paul, writing in Galatians 4:29, calls the same event “persecution.” Whatever the exact nature of the act, the text treats it as the decisive moment that set in motion the separation of the two sons, a separation God soon confirmed.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Malicious mockery: The Piel intensive form of the verb suggests intensity; Paul calls it persecution (Galatians 4:29); Sarah’s fierce reaction and God’s confirmation imply serious offense.
- Innocent play misinterpreted: The same verb is used positively for Isaac’s name and for playful laughter; the LXX and Vulgate add 'with Isaac,' suggesting normal child’s play; Sarah may have reacted from possessive jealousy.
- Something more severe (physical or ritual): Rabbinic traditions (Targumim) and some early Christian writers speculated about idolatry, indecency, or attempted violence; though these go beyond the text’s explicit words, they reflect a longstanding attempt to justify the expulsion by the gravity of the act.
What is clear: Sarah saw Ishmael do something with or to Isaac that she considered a threat to Isaac’s place in the family, and her demand for expulsion was later confirmed by God.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Nature of Ishmael's action | Sarah saw Ishmael doing something that provoked her demand for expulsion; the Hebrew word <em>metsachaq</em> is the same root as Isaac's name. | Some interpreters see it as malicious mockery or persecution (Calvin, Gill, Matthew Henry, Paul in Galatians 4); others argue the verb means 'playing' and that Sarah overreacted from jealousy (Cambridge Bible, LXX/Vulgate addition). |
| Paul's use of 'persecution' in Galatians 4:29 | Paul connects this event to the relationship between the flesh and the Spirit. | Some take Paul's wording as definitive proof that Ishmael's mocking was severe persecution; others note that Paul is using an interpretive tradition that may go beyond the literal sense of the Hebrew. |
| Sarah's role in the expulsion | Sarah initiated the demand to cast out Hagar and Ishmael, and God later confirmed it. | Some see Sarah's action as faithful protection of the covenant line (God backs her); others see her as harsh and potentially overstepping, with God accommodating her protective instincts (v. 11 shows Abraham was grieved). |
| Date of the four hundred years of affliction (Genesis 15:13) | Some interpreters connect this event to the beginning of Israel's affliction in Egypt due to Hagar's Egyptian origin. | Others see the connection as speculative, reading back a later theological pattern into an earlier narrative. |
| Ishmael's age at the time | Ishmael was born when Abraham was 86, Isaac when Abraham was 100, so Ishmael was around 14 at Isaac's weaning. | The exact age of Isaac at weaning is uncertain (some Jewish sources suggest 2, 5 years; the text does not specify), which affects how one interprets the interaction between the two boys. |
Historical & Cultural Context
The verse sits within a pivotal narrative. Isaac has just been weaned, a milestone in the ancient world, often celebrated with a feast (v. 8). Abraham is one hundred years old; Isaac is likely two or three. Ishmael, born when Abraham was eighty-six, is about fourteen. He is the firstborn son, but the promise has been explicitly given through Isaac (Genesis 17:19). Ishmael’s position has shifted: he is no longer the presumptive heir.
The feast would have been a public acknowledgment of Isaac’s status. Sarah, watching from nearby, sees Ishmael’s behavior. The text calls her attention to his identity: “the son of Hagar the Egyptian”, language that subtly distances him from the covenant family. Hagar’s Egyptian origin (Genesis 16:1, 3) ties the scene to a broader pattern of tension, and some commentators see in this the beginning of the four hundred years of affliction prophesied in Genesis 15:13.
Sarah’s reaction is immediate and fierce: she demands the expulsion of the slave woman and her son (v. 10). Abraham is distressed, but God tells him to listen to Sarah, confirming that Isaac is the line of the covenant and that Ishmael will also be made a nation (vv. 12, 13). The cultural background of a weaning feast, the ages of the boys, and the legal context of inheritance all frame the confrontation. It is a family conflict with enormous theological stakes: which son inherits the promise?
Textual Notes
The consulted sources note no significant textual variants in the Hebrew of Genesis 21:9. The Masoretic Text reads מְצַחֵק (metsachaq) consistently. The Greek Septuagint and Latin Vulgate add an object: “playing with Isaac her son” (παίζοντα μετὰ Ἰσαὰκ τοῦ υἱοῦ αὐτῆς; ludentem cum Isaac filio suo). This addition likely represents an interpretive expansion rather than a different Hebrew Vorlage, and it shapes how the verse has been read in many traditions. The supplied commentary from Cambridge Bible explicitly prefers this reading and places “mocking” in the margin. No other variants are mentioned in the supplied materials.
Reception History
This verse has been read in at least three ways across church history. The earliest known interpretation is Paul’s in Galatians 4:21, 31, where he calls Ishmael’s action “persecution” and allegorizes the conflict as between the flesh and the Spirit. Jewish traditions, recorded in the Targums and rabbinic sources (mentioned by Clarke and Cambridge Bible), saw Ishmael engaged in idolatry, immorality, or even attempted murder. Early Christian commentators like Augustine followed Paul’s allegorical reading. Medieval Jewish exegetes like Rashi favored the “mocking” sense, connecting it to ridicule of Isaac’s birth. Protestant Reformers (Calvin, Luther) stressed the mockery of God’s promise, with Calvin calling it “impious mockery.” Puritan commentators (Matthew Henry) emphasized the sinfulness of mocking and God’s notice of children’s behavior. Modern scholarship often weighs the semantic range of the Hebrew, some leaning toward “playing” (Cambridge Bible) and others toward “mocking” (NIV, ESV). The verse remains a touchpoint in discussions of typology, covenant, and the limits of allegorical interpretation.
Preaching This Verse
Three-point outline
- The action observed. Sarah saw. The Hebrew verb רָאָה (ra’ah) implies more than casual sight, she watched and perceived. What she saw became a turning point.
- The reaction demanded. Sarah’s response was not petty; she saw a threat to Isaac’s place. She named the offense as disqualifying Ishmael from heirship.
- The divine confirmation. God backed Sarah’s demand, not because of her temper but because the covenant must run through Isaac. Yet God also promised to make a nation of Ishmael.
Five-point outline
- A feast of joy. Weaning Isaac was a cause for celebration, fulfillment of God’s promise.
- A conflict in plain sight. Sarah saw something that troubled her. The Hebrew participle leaves room for ambiguity: mocking or playing.
- A mother’s protective demand. Sarah drew a hard line. Her language (“cast out”) is harsh but echoes God’s own later command.
- A father’s torn heart. Abraham was grieved. He loved Ishmael. But God’s word clarified the choice.
- A promise for both sons. Isaac inherits the covenant; Ishmael becomes a great nation. God’s purposes are not small.
Illustration hooks
- Schoolyard conflict. A parent sees an older child teasing a younger one, not violent, but cutting. The line between play and cruelty is thin. Perspective matters.
- Mixed signals at work. A coworker’s joke lands differently depending on history and power dynamics. What feels like fun to one person feels like a threat to another.
Questions your congregation is asking
- Was Ishmael really being malicious, or did Sarah overreact? Does it matter?
- How do we know when playful behavior has crossed into mockery?
- Why would God support such a harsh expulsion when He loved Ishmael too?
Leading a Discussion
This passage challenges us to think about how conflict, perception, and divine purpose intersect. Sarah saw something that looked like a threat to Isaac’s future in the covenant. But was it truly malicious, or did she read it wrong? The text leaves room for both readings. As you talk through these questions, try to hold both the family drama and the theological stakes in view.
Discussion questions
- Observation: What exactly does the text say Ishmael did? What words are used to describe his action?
- Observation: How does Sarah describe the situation when she speaks to Abraham in v. 10? What does that tell you about what she perceived?
- Interpretation: The Hebrew word metsachaq can mean “to mock” or “to play.” Which meaning fits better with the surrounding story? Why do you think the translators of different versions chose different renderings?
- Interpretation: How does Paul’s reading of this event in Galatians 4:29 affect how you understand it? Does Paul settle the debate about the nature of Ishmael’s action?
- Interpretation: Why does God tell Abraham to listen to Sarah (v. 12)? What does that suggest about God’s view of the conflict?
- Application: Have you ever witnessed a situation where one person’s “play” felt like a threat to someone else? How do we discern the difference?
- Application: This family was caught between covenant promise and natural affection. How can churches today navigate hard family decisions while trusting God’s larger purposes?

What the Commentators Say
9 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke notes that the exact nature of Ishmael's mocking is unknown. However, he draws a significant connection: the persecution of Isaac by the son of an Egyptian woman may mark the beginning of Israel's four hundred years of Egyptian bondage mentioned in Genesis.
Calvin's Commentaries Reformed 1564
Calvin draws a sharp contrast between two kinds of laughter: Isaac's name comes from the holy joy of God's promise, while Ishmael's scornful mockery attacks that same grace. Sarah's fierce reaction is justified, because ridiculing God's blessing is no small offense.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentary argues that the Hebrew verb here simply means playing rather than mocking, as it lacks a direct object. This reading suggests Sarah felt sudden jealousy watching Ishmael play near Isaac, viewing such closeness as unfitting given his status as her handmaid’s son. It notes that later interpretations, including Paul’s reference in Galatians, expanded this neutral action into accusations of teasing or persecution.
Geneva Bible Notes Reformed 1599
The Geneva annotators treat this as more than a child's teasing. They see Ishmael's mocking as outright persecution, revealing his contempt for Isaac and the covenant line. This interpretation makes Sarah's harsh response understandable as protecting the promised seed and the spiritual inheritance.
Gill's Exposition of the Bible Baptist 1748
Gill sees Ishmael's mocking as a serious fight over the inheritance, not mere childish play. He argues the word can mean physical beating, which is why Paul calls it persecution. He dismisses Jewish traditions about idolatry or indecent talk as unfounded.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB points out that Ishmael's mocking was no childish play but a resentful outburst driven by his awareness that Isaac had displaced him. He suggests Hagar likely shared this bitterness, and that the persecution went beyond words to rough treatment, as Paul later recalls in Galatians.
Lange's Commentary Reformed 1857
Lange notes that the shift to the divine name Elohim in this chapter reflects God’s general providence over Ishmael and His interaction with Abimelech, who did not yet know Jehovah. This usage highlights how the narrative weaves together different sources while maintaining unity, showing Isaac as a child given under God’s overarching care rather than solely through the covenant name.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry sees Ishmael's mocking as no mere childish prank but a serious sin that God observes and will reckon with. He notes that Ishmael, being much older, ought to have protected his younger brother, and he links this persecution to the pattern Paul later describes in Galatians.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley sees the mockery as persecution of the Spirit-born child by the flesh-born child, linking it to Galatians. He also suggests that calling Ishmael "the son of the Egyptian" signals the beginning of the four hundred years of affliction Abraham's seed would suffer from the Egyptians.
