Genesis 38:8 Explained in Context
Use this verse as a doorway into the larger passage—not as an isolated saying.
Verse 8. 8And Judah said unto Onan, Go in unto thy brother’s wife, and marry her, and raise up seed to thy brother.
King James Version — public domain in the United States · Bible text and permissions
Quick Meaning
Judah tells Onan to have sexual relations with Tamar, perform the brother-in-law family duty, and raise offspring for his deceased brother. The command concerns family continuity and Tamar's place, not ordinary marriage advice detached from this social setting.
Read It With
- Genesis 38:1–30
Read verses 7–11 and compare Deuteronomy 25:5–10 cautiously. Er's death creates the need, verse 9 describes Onan's refusal while using Tamar sexually, and verse 11 shows Tamar left waiting for Shelah.
Why This Verse Appears Here
Judah's instruction defines the family responsibility Onan knowingly refuses and establishes why Tamar remains connected to Judah's household.
Read Genesis 38:6–11 together
Why these verses belong together: Tamar's marriage, Er's unexplained evil, Onan's family-duty refusal, both deaths, and Judah's conditional promise form one family-obligation crisis.
Verse 6. 6 And Judah took a wife for Er his firstborn, whose name was Tamar.
Verse 7. 7 And Er, Judah’s firstborn, was wicked in the sight of the LORD; and the LORD slew him.
Verse 8. 8 And Judah said unto Onan, Go in unto thy brother’s wife, and marry her, and raise up seed to thy brother.
Verse 9. 9 And Onan knew that the seed should not be his; and it came to pass, when he went in unto his brother’s wife, that he spilled it on the ground, lest that he should give seed to his brother.
Verse 10. 10 And the thing which he did displeased the LORD: wherefore he slew him also.
Verse 11. 11 Then said Judah to Tamar his daughter in law, Remain a widow at thy father’s house, till Shelah my son be grown: for he said, Lest peradventure he die also, as his brethren did. And Tamar went and dwelt in her father’s house.
Follow the Context
- Judah separates from his brothers, forms a household with the daughter of Shua, and fathers Er, Onan, and Shelah (38:1–5).
- Judah gives Tamar to Er; after Er dies, Onan repeatedly refuses the family duty to raise offspring for his brother and also dies (38:6–10).
- Judah sends Tamar to her father's house to wait for Shelah, but fear keeps him from giving Shelah after the son has grown (38:11–14).
- Judah mistakes the veiled Tamar for a prostitute; she negotiates his signet, cord, and staff as security, conceives, and departs (38:15–19).
- Hirah cannot find the woman; the local inquiry uses a different prostitution term, and Judah stops the search to avoid public contempt (38:20–23).
- Judah orders Tamar burned when her pregnancy is reported, but her identifying evidence makes him recognize that she is more in the right because he withheld Shelah (38:24–26).
- Tamar bears twins; a scarlet thread first marks Zerah's extended hand, but Perez breaks out first and receives the breach name (38:27–30).
Phrase-by-Phrase Explanation
“go in unto thy brother's wife”
In plain language: Judah directs Onan to have sexual relations with Tamar in the family-duty arrangement.
The older idiom is sexual, not merely entering a room.
Why it matters: Clear language prevents the obligation from being hidden behind euphemism.
How certain? very strong“marry her”
In plain language: The KJV renders the verb for performing the brother-in-law duty.
The issue is raising offspring for the deceased brother and securing family continuity.
Why it matters: It must not be flattened into ordinary modern marriage advice.
How certain? very strong“raise up seed to thy brother”
In plain language: The expected child would continue the deceased brother's line.
Onan knows the offspring would not be counted as his.
Why it matters: His later refusal is deliberate and relational.
How certain? very strongWhat This Verse Is Not Saying
This verse does not command every widow to marry a brother-in-law.
The verse does not make a woman property transferred between men.
The command does not authorize coercive sex or remove Tamar's human dignity.
Genesis 38 does not reproduce every procedure of the later Deuteronomy 25 law.
What Remains True
Family responsibility includes protecting a vulnerable survivor's future rather than using tradition or relationship for personal advantage.
How It Can Shape Life
- Where law or custom creates responsibility toward a dependent survivor, honor the protective purpose and use fair current legal processes rather than exploiting technicalities.
