Ecclesiastes 1:17 - And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation H7475 of spirit.
Ecclesiastes 2:22 - For what hath man of all his labour, and of the vexation H7475 of his heart, wherein he hath laboured under the sun?
Ecclesiastes 4:16 - 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 H7475 of spirit.
