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.
GENESIS 38:9KJVWhat does Genesis 38:9 mean?
Genesis 38:9 describes how Onan, knowing that any child born from his union with his brother’s widow would not be considered his own heir, deliberately prevented conception by spilling his semen on the ground. Onan did this to avoid producing offspring for his deceased brother, as was expected by family duty.
In this story, Judah’s son Onan is told to fulfill the custom of levirate marriage by having a child with his late brother’s wife, Tamar, so that his brother’s family line would continue. Instead, Onan chooses not to fulfill this responsibility, acting for his own interests rather than honoring his family obligation. This verse sets up the consequences that follow for Onan’s actions in the next verses.
The Hebrew behind Genesis 38:9
- "seed" (זֶרַע, zeraʿ): This word means "offspring" or "descendants," not just literal seed. The verse uses it to show that the child would be counted as the brother’s, not Onan’s own.
- "spilled" (שָׁחַת, shāḥat): This word often means "to destroy" or "to ruin." Here, it describes Onan’s intentional act to prevent conception, emphasizing that he actively thwarted the expected outcome.
- "lest" (בִּלְתִּי, biltî): This word signals Onan’s motive—he acted this way specifically to avoid giving offspring to his brother.
Why Genesis 38:9 matters
- Genesis 38:9 clarifies that Onan’s wrongdoing was not simply the act itself, but his refusal to fulfill his family duty and provide an heir for his brother.
- The verse highlights the importance of family loyalty and responsibility in ancient Israelite society, especially regarding inheritance and the continuation of a family line.
- Understanding the motives and customs at play helps clear up common misunderstandings about why Onan’s actions were considered so serious in the context of this story.
