Jeremiah 31:30
“But everyone will die for his own iniquity. Every man who eats the sour grapes, his teeth will be set on edge.”
What does Jeremiah 31:30 mean?
Jeremiah is responding here to a proverb his people used: "the fathers have eaten sour grapes, and the children's teeth are set on edge." That saying reflected a belief that children suffer for their parents' sins, that punishment passes down through generations. Jeremiah pushes back against this, insisting that God holds each person accountable for their own choices, not their family's failures. The teeth-setting image describes the immediate, personal consequence of wrongdoing, like a bitter taste you bring on yourself. This was actually radical comfort for people in exile, because it meant they weren't trapped in endless cycles of inherited guilt, and it meant God's judgment was fair and personal rather than arbitrary.
