'Generation' in the Bible

Night and day it shall not be quenched; its smoke shall go up forever. From generation to generation it shall be in ruins; forever and ever there will be no one who passes through her.

And he {is the one that} has cast [the] lot for them, and his hand has apportioned it to them with the measuring line; they shall take possession of it forever, they shall live in it {from generation to generation}.

For a moth will eat them like garments; a moth will devour them like wool, but my righteousness will be forever, and my salvation for {generation after generation}."

He was taken by restraint of justice, and who concerned himself with his generation? For he was cut off from the land of [the] living; he [received a] blow because of the transgression of my people.
