Genesis 38:10 vividly highlights that God holds His people accountable and does not tolerate deliberate wrongdoing.
Judah, who lived around 1900-1700 BC, was one of the twelve sons of Jacob and resided in the region of Canaan. He had three sons: Er, Onan, and Shelah. When Er died childless, Judah instructed his second son Onan to fulfill the levirate duty and produce an heir for his late brother’s widow, Tamar, so that Er’s name and legacy might continue. However, Onan selfishly refused to provide Tamar with an heir, seeking to preserve his own inheritance rather than carry on his brother’s line, a practice that was condemned as greedy and unfaithful in the scriptural tradition.
Scripture describes this act by saying, “But what he did was displeasing in the sight of the LORD; so He took his life also.” (v.10) Onan deliberately thwarted the levirate principle by preventing Tamar from conceiving Er’s offspring (Genesis 38:9). According to the law later formalized for Israel, refusing to raise up offspring for a deceased brother showed contempt not only for the widow’s provision, but also for God’s covenant design. As a result, the passage demonstrates the seriousness with which God regards obedience to family and covenant responsibilities, holding individuals accountable for hidden or self-serving motives.
By ending Onan’s life, God underscored the principle that He sees beyond outward actions to the intentions of the heart. The timing of this narrative in Judah’s lineage further shows how a single act of disobedience could disrupt generational blessings, linking this passage both to future commands on levirate marriage and to the overarching theme of God’s steadfast justice.
