# Fathers have eaten sour grapes, but the children's teeth are dulled
A proverb that Jeremiah heard people say when they were complaining that Yahweh was punishing children for the sins of their fathers. The ULB sets 31:29 farther to the right than the rest of the text since it is an important quotation.
# sour grapes
grapes with too much acid in them or grapes that are not ripe
# teeth are dulled
