Ecclesiastes 2:11 Thus I considered all my activities which my hands had done and the labor which I had exerted, and behold all was vanity and striving after wind and there was no profit under the sun.

Ecclesiastes 2:17 So I hated life, for the work which had been done under the sun was grievous to me; because everything is futility and striving after wind.

Ecclesiastes 4:4 I have seen that every labor and every skill which is done is the result of rivalry between a man and his neighbor. This too is vanity and striving after wind.

Ecclesiastes 6:9 What the eyes see is better than what the soul desires. This too is futility and a striving after wind. (NASB ©1995)
