Read Ecclesiastes 4:16 Using Other Translations
There is no end of all the people, even of all that have been before them: they also that come after shall not rejoice in him. Surely this also is vanity and vexation of spirit.
There was no end of all the people, all of whom he led. Yet those who come later will not rejoice in him. Surely this also is vanity and a striving after wind.
Endless crowds stand around him, but then another generation grows up and rejects him, too. So it is all meaningless—like chasing the wind.
