'Generation' in the Bible

“O generation, heed the word of the Lord.Have I been a wilderness to Israel,Or a land of thick darkness?Why do My people say, ‘We are free to roam;We will no longer come to You’?

‘Cut off your hair and cast it away,And take up a lamentation on the bare heights;For the Lord has rejected and forsakenThe generation of His wrath.’

“Therefore the desert creatures will live there along with the jackals;The ostriches also will live in it,And it will never again be inhabitedOr dwelt in from generation to generation.
