Lessons from Er and Onan's fate?
What lessons can we learn from Er and Onan's fate in Numbers 26:19?

The Setting in Numbers 26:19

“The sons of Judah were Er and Onan, but they died in the land of Canaan.” (Numbers 26:19)


The Story Behind the Names

Genesis 38 records the original events:

• “But Er, Judah’s firstborn, was wicked in the sight of the LORD; so the LORD put him to death.” (Genesis 38:7)

• “What he did was wicked in the sight of the LORD; so He put Onan to death as well.” (Genesis 38:10)

Their removal is so significant that, centuries later, the census in Numbers still notes their absence.


Key Lessons from Their Fate

• Sin is never private. Er’s unnamed wickedness and Onan’s deliberate refusal to obey God’s command about offspring carried community repercussions and cut off their own legacy.

• God judges unrighteousness decisively. His holiness cannot tolerate unrepentant wickedness (Leviticus 10:3; Hebrews 10:31).

• Half-hearted obedience equals disobedience. Onan performed the outward act while rejecting its purpose; God sees the motives (1 Samuel 16:7).

• Covenant privileges do not cancel personal responsibility. Though sons of Judah, they forfeited blessing through persistent sin (Romans 11:22).

• The census reminds every generation that God’s verdicts stand. What He once judged remains judged unless grace intervenes through repentance.

• Divine discipline safeguards the covenant line. By removing Er and Onan, God preserved the purity and future of Judah’s tribe, through which the Messiah would come (Genesis 49:10; Matthew 1:3).


Application for Today

• Cultivate wholehearted obedience; partial compliance invites discipline.

• Guard motives as carefully as actions; God weighs the heart.

• Take sin seriously; swift repentance restores fellowship (1 John 1:9).

• Value your spiritual legacy; today’s choices echo into future generations (Deuteronomy 30:19-20).

• Marvel at grace: though two sons fell, God still advanced His redemptive plan through Judah, proving His mercy even amid judgment.
