'Generation' in the Bible

O generation, see ye the word of Jehovah. Have I been a wilderness unto Israel? or a land of thick darkness? wherefore say my people, We are broken loose; we will come no more unto thee?

Cut off thy hair, O Jerusalem , and cast it away, and take up a lamentation on the bare heights; for Jehovah hath rejected and forsaken the generation of his wrath.

Therefore the wild beasts of the desert with the wolves shall dwell there, and the ostriches shall dwell therein: and it shall be no more inhabited for ever; neither shall it be dwelt in from generation to generation.
