'Generation' in the Bible

“O generation [that you are], consider and regard carefully the word of the Lord.Have I been a wilderness to Israel [like a land without food],A land of thick and deep darkness [like a path without light]?Why do My people say, ‘We [have broken loose and we] are free to roam [at will];We will no longer come to You’?

‘Cut off your hair [your crown, O Jerusalem] and throw it away,And take up a mournful cry on the barren heights,For the Lord has rejected and abandonedThe generation of His wrath.’

“Therefore wild beasts of the desert will live there [in Babylon] with the jackals;The ostriches also will live there,And it will never again be inhabited [with people]Or lived in from generation to generation.
