Ecclesiastes 4:4; Ecclesiastes 4:6; Ecclesiastes 4:16
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.
Better is a handful of quietness than two hands full of toil and a striving after wind.
there was no end of all the people; he was over all of them. Yet those who come later will not rejoice in him. Surely this also is vanity and a striving after wind.
