Scholars' Consensus
Commentators agree that Migdal-Eder ("tower of the flock") designates a shepherd's watchtower near Bethlehem, possibly the site where shepherds later received the angelic announcement of Christ's birth (Luke 2:8). Both Gill and Clarke note the Targumic tradition that connects this place to the manifestation of the King Messiah. On Reuben's act, the consensus holds that he committed a grave sin by lying with his father's concubine Bilhah. Calvin calls it "incestuous intercourse" and "detestable dishonor"; Henry says it was "abominable wickedness." The commentators further observe that the narrative breaks off abruptly after "Israel heard it," with Keil and Delitzsch explaining the piska (textual pause) as a parashah division, not a gap. The final summary of Jacob's twelve sons is seen as a deliberate structural marker: despite the family's sin, the covenant people are preserved and numbered.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Literal-historical: Reads the incest as a real event, supported by the context of Genesis 49:3-4 and the cultural significance of concubinage.
- Mitigating (Targumic): Reuben only overturned Bilhah's bed, not actual intercourse; based on Targum Jonathan and a desire to protect the patriarchs' reputation.
- Symbolic/tribal: The story reflects later tribal conflicts: Reuben's tribe lost pre-eminence, and this narrative explains its decline (Cambridge Bible).
What is clear: The passage records a grievous breach of family honor that alienated Reuben from his father and led to the loss of his birthright, yet the covenant line continued through Jacob's twelve sons.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Location of the tower of Eder | It is a shepherd's watchtower near Bethlehem, fitting the pastoral context of Jacob's journey. | Some identify it precisely with a site south of Bethlehem (traditional since Jerome); others see it as a general region, not a specific spot. |
| Nature of Reuben's act | It is presented as a serious sin that dishonored Jacob and cost Reuben his birthright (Genesis 49:3-4). | A Targumic tradition holds that Reuben only overturned Bilhah's bed in protest of her being preferred over Leah, not actual intercourse. Most Christian commentators (Calvin, Henry, Gill) read it as literal incest. |
| Jacob's silence | The text records that 'Israel heard it' but gives no reply, leaving the emotional impact implicit. | Some interpret this as stunned grief (Calvin); others as a literary device or textual gap (Clarke notes the hiatus). Keil and Delitzsch see it as a normal parashah pause. |
| Connection to the shepherds of Luke 2 | Both Micah 4:8 and early tradition (Targum Jonathan) link the tower of the flock to the Messiah's revelation. | Some commentators make a firm typological connection; others caution that the identification is not certain and may be later pious speculation. |
Historical & Cultural Context
Jacob's journey from Bethel continues southward toward Hebron, where his father Isaac still lives. He pitches his tent "beyond the tower of Eder", a location that the Cambridge Bible situates between Ephrath (Bethlehem) and Hebron. The "tower of the flock" was a stone watchtower used by shepherds to guard sheep at night, common in the pastoral hill country. This region later became associated with the birth of David and, centuries later, with the announcement of the Messiah's birth to shepherds (Micah 4:8; Luke 2:8). Early Jewish tradition, cited by Clarke in the Targum of Jonathan, explicitly linked this tower to the place "where the King Messiah shall be manifested."
The second event, Reuben sleeping with Bilhah, must be understood in its cultural context. Bilhah was Jacob's concubine, a servant wife given by Rachel (Genesis 30:5). By lying with her, Reuben committed incest (Leviticus 18:8) and challenged his father's authority. Such an act threatened the family hierarchy and the transmission of the birthright. The brief report, with only "Israel heard it," suggests a stunned silence. Calvin writes that the grief was "too great to be expressed." Later, in Genesis 49:3-4, Jacob recalls this sin when he strips Reuben of his primogeniture. The placement of the twelve-son list immediately after the scandal shows God's grace continuing through the family despite human failure. The narrative thus holds together judgment and promise, tragedy and the ongoing story of redemption.
Textual Notes
The consulted sources note that the Hebrew text of verse 22 marks a piska (a pause or space) after "Israel heard of it." Keil and Delitzsch explain this as the conclusion of a parashah (a division of the text), older than the Masoretic chapter breaks. Clarke mentions that the Septuagint adds "and it appeared evil in his sight" to supply Jacob's implied response. No significant variants affecting the meaning of the passage are reported in standard critical editions; the main interpretive issue is whether the pause reflects a lacuna or a natural literary break.
Reception History
Early Jewish tradition, preserved in the Targum of Jonathan, offered a mitigated reading: Reuben did not actually sleep with Bilhah but only moved her bed to protest his mother Leah's dishonor. Christian exegetes from the Reformation onward (Calvin, Henry, Gill) read the episode literally as incest and emphasized its gravity. The tower of Eder, meanwhile, was venerated from at least the time of Jerome as the site where shepherds saw angels announce Christ's birth. Medieval and modern interpreters often treat the passage as a dark prelude to the list of the twelve tribes, showing that God's purposes are not derailed by human sin. Many hymns and sermons on Luke 2 have referenced "the tower of the flock" as a place where divine light broke into a broken world.
Preaching This Verse
Three-point outline
- The geography of hope, Jacob pitches his tent near the tower of the flock, a place that tradition and later Scripture connect to the coming Shepherd-King (Micah 4:8; Luke 2:8). Even in the midst of mourning Rachel, the journey points forward to a greater hope.
- Sin in the chosen family, Reuben's incestuous act shows that even those within the covenant are capable of deep depravity. The narrative does not excuse it, nor does it dwell on it; it simply reports it, leaving the reader to feel the weight of the silence.
- The perseverance of the promise, The list of twelve sons immediately follows the scandal. God does not abandon his plan. The covenant continues through flawed people and broken families.
Five-point outline
- Journeying toward home, Jacob/Israel moves from Bethel to the tower of Eder, toward his aging father Isaac (v. 21).
- A place of flocks and future, The tower of the flock marks a location later honored as the site of the shepherds' announcement (v. 21).
- A son's rebellion, Reuben's sin with Bilhah brings shame and a broken relationship with his father (v. 22a).
- The heavy silence, "Israel heard it", no recorded response, only a pause in the text (v. 22b).
- The twelve sons, Despite the rupture, the family of promise stands complete (v. 22c).
Illustration hooks
- A successful family business shattered by a child's moral failure. The father says nothing publicly, but the silence is felt for years.
- A church known for its beautiful nativity scene learns that the shepherds' field was also a place where a patriarch's son fell into disgrace. Redemption often starts in messy places.
- The contrast between a watchtower built to guard sheep and a broken home where no one was watching. Both are part of the same story.
Questions your congregation is asking
- Why does the Bible include such an ugly story without giving us Jacob's reaction?
- How can God continue to work through a family with this kind of sin?
- Does the tower of Eder really connect to the shepherds at Jesus' birth, or is that later tradition?
Leading a Discussion
This passage forces us to sit with two very different realities. On one hand, Israel camps at a place that will become a symbol of hope, the tower of the flock. On the other hand, the family is shattered by Reuben's sin. The text moves quickly from one to the other, as if to say that both are part of the same story. As you discuss these verses, pay attention to the gaps: Jacob's silence, the sudden list of sons, the unresolved tension. What does this teach us about how God works through broken people?
Discussion questions
- What do you know about the tower of Eder from the Old Testament and later tradition? Why do you think the author includes this detail?
- Read Micah 4:8 and Luke 2:8. How do these passages connect to Genesis 35:21? Does the location matter for understanding God's plan?
- Why does the narrator call Jacob "Israel" in verses 21-22 but then list "the sons of Jacob" in verse 22? What might this shift in names mean?
- Reuben's sin is described briefly. What might be the significance of the pause in the Hebrew text and the lack of any recorded response from Jacob?
- How does the list of twelve sons function in the narrative after the scandal? What does it say about God's faithfulness?
- In what ways do we see the consequences of Reuben's sin later in Genesis (cf. 49:3-4)? How does this story shape our understanding of repentance and restoration?
- What does this passage teach us about hope in the midst of family brokenness? How can we apply that to our own lives and churches?

What the Commentators Say
9 public-domain commentaries, condensed into plain language.
Adam Clarke's Commentary Methodist/Wesleyan 1826
Clarke notes that the Hebrew text leaves a deliberate break after “Israel heard it,” suggesting something is missing. He reports a Jewish tradition that Reuben only overturned Bilhah’s bed in anger, not actually sleeping with her, though the Septuagint adds that the act seemed evil in Jacob’s sight.
Calvin's Commentaries Reformed 1564
Calvin sees Reuben's crime not merely as a family scandal but as Satan's deliberate attempt to discredit God's elect by covering grace with infamy. He adds that God permits such humiliations to keep His people humble, watchful, and wholly dependent on mercy. The narrator's silence on Jacob's grief, Calvin suggests, indicates a sorrow too deep for words.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentary treats Reuben’s act not merely as personal sin but as a figurative memory of early tribal rivalry over primogeniture. It suggests that Rachel’s death at Benjamin’s birth symbolizes the new tribe replacing the old identity associated with her name. This reading links personal events to broader tribal shifts rather than viewing them as isolated family incidents.
Geneva Bible Notes Reformed 1599
The Geneva Bible highlights a stark contrast between Jacob’s physical journey forward and the moral decay within his household. It records Reuben’s sin with Bilhah as a private shame that nonetheless reached Jacob’s ears, signaling the beginning of familial fracture. The note underscores this tragedy by immediately stating Jacob still had twelve sons, preserving the lineage despite the internal corruption.
Gill's Exposition of the Bible Baptist 1748
Gill notes this is the first passage where Moses calls Jacob "Israel," which Jewish tradition explains as a reward for his patient endurance of Rachel's death. He interprets Reuben's sin as a divine chastisement on Jacob for having concubines, and observes that the Hebrew text leaves a pause showing Jacob's speechless shock.
Keil & Delitzsch OT Commentary Protestant 1876
Keil and Delitzsch note that the piska in the middle of verse 22 is not a textual gap but an ancient parashah division. They see the list of Jacob's twelve sons, arranged by their mothers, as deliberately placed to show how the faithful covenant God blessed Jacob from a staff to a great family.
Lange's Commentary Reformed 1857
Lange interprets Reuben’s crime as happening while Jacob was likely away visiting Isaac, leaving Reuben in temporary household authority. Jacob’s quiet response, “and Israel heard it,” reflects not weakness but a deliberate, spiritually mature forbearance. This incident later cost Reuben his birthright, as Genesis 49:4 records.
Matthew Henry's Commentary Reformed/Presbyterian 1710
Henry observes that Jacob is called Israel immediately after Rachel's death because the historian honors his patient submission to Providence under that heavy affliction. True Israelites, princes with God, are those who rule their own spirits through suffering and dwell in tents while awaiting their city in the other world.
Wesley's Explanatory Notes Methodist/Wesleyan 1754
Wesley observes that Jacob, though a prince with God, still lived in tents because the true city is reserved for the next world. He notes that Reuben's sin cost him his birthright and blessing, and that Jacob's silent grief speaks louder than any words.
