But Onan knew
The name "Onan" is derived from the Hebrew root "אוֹנָן" (Onan), meaning "vigorous" or "strong." This introduction to Onan's actions sets the stage for understanding his motivations and the consequences of his choices. In the context of ancient Hebrew culture, the knowledge that the offspring would not be his reflects a deep understanding of the levirate marriage custom, where a brother was expected to produce offspring for his deceased brother to preserve the family line.

that the offspring would not be his
The Hebrew word for "offspring" is "זֶרַע" (zera), which can also mean "seed" or "descendants." This highlights the importance of lineage and inheritance in ancient Israelite society. The phrase underscores Onan's awareness of the cultural and familial obligations he was expected to fulfill. His reluctance to provide offspring for his brother indicates a selfish prioritization of personal gain over familial duty.

so whenever he slept with his brother’s wife
The act of sleeping with his brother's wife, Tamar, was not merely a physical act but a fulfillment of a social and religious duty. The Hebrew term for "slept" is "שָׁכַב" (shakab), which often implies a deeper covenantal or relational aspect. This phrase emphasizes the repeated nature of Onan's actions, suggesting a willful and ongoing defiance of his responsibilities.

he spilled his seed on the ground
The act of spilling his seed, described by the Hebrew word "שָׁחַת" (shachat), meaning "to destroy" or "to waste," is a deliberate act of disobedience. In the ancient Near Eastern context, this act was seen as a grave violation of duty, as it thwarted the continuation of the family line. The imagery of seed being wasted on the ground symbolizes the loss of potential life and blessing.

to keep from providing offspring for his brother
This phrase highlights Onan's intentionality in preventing the birth of an heir for his brother. The Hebrew word "לְבִלְתִּי" (levilti) means "to not" or "in order not to," indicating a purposeful decision. Onan's actions reflect a deeper spiritual rebellion against God's design for family and community, as well as a disregard for the well-being of his brother's legacy.

Verses 9, 10. - And Onan knew that the seed should not be his; and it came to pass, when - literally, and it was if, i.e. whenever (cf. Ewald, Hebrews Synt., § 3456) - he went in unto his brother's wife, that he spilled it on the ground (literally, destroyed to the ground), lest that he should (or, so as not to) give seed to his brother. And the thing which he did displeased (literally, was evil in the eyes of) the Lord: - the word Jehovah is employed not because the writer was a late interpolator, but because the sin of Onan was an offence against the sanctity and prosperity of the theocratic family (Hengstenberg) - wherefore he (i.e. Jehovah) slew him also (vide supra).
