Genesis 4:13
And Cain said unto the Lord, My punishment is greater than I can bear.
Cross-reference
In Lam. 3:39, the living are asked why they complain about their just punishment — the exact logic applied to Cain's protest here.
In 2 Cor. 7:10, worldly sorrow brings death — contrasting with Cain's despair. His complaint is an example of sorrow without repentance.
In Revelation 16:9, those scorched by plagues curse God instead of repenting — contrasting with Cain, who at least acknowledges the weight of his punishment.
In Revelation 16:11, the afflicted curse heaven's God and refuse to repent — echoing the theme of suffering under judgment, though with different responses.
In Revelation 16:21, the terrible hail prompts cursing God — another instance of harsh punishment met with complaint, like Cain's outcry over his sentence.
