'Generation' in the Bible

O generation, you see the word of Yahweh. Have I been a desert to Israel? Or a land of great darkness? Why do my people say, 'We roam about freely, we will not come again to you'?

Shear your hair and throw [it] away, and lift up a lament on the barren heights, for Yahweh has rejected and forsaken the generation of his wrath.'
