'Generation' in the Bible

There is a generation who put a curse on their father, and do not give a blessing to their mother.

There is a generation who seem to themselves to be free from sin, but are not washed from their unclean ways.

There is a generation, O how full of pride are their eyes! O how their brows are lifted up!

There is a generation whose teeth are like swords, their strong teeth like knives, for the destruction of the poor from the earth, and of those who are in need from among men.
