Ecclesiastes 4:4, 8, 16
Ecclesiastes 4:4 ESV
Then I saw that all toil and all skill in work come from a man’s envy of his neighbor. This also is vanity and a striving after wind.
Ecclesiastes 4:16 ESV
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.
