Ecclesiastes 1:13 And I set my mind to seek and explore by wisdom concerning all that has been done under heaven. It is a grievous task which God has given to the sons of men to be afflicted with.

Ecclesiastes 1:14 I have seen all the works which have been done under the sun, and behold, all is vanity and striving after wind.

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 2:12 So I turned to consider wisdom, madness and folly; for what will the man do who will come after the king except what has already been done?

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 4:6 One hand full of rest is better than two fists full of labor 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.

Ecclesiastes 7:25 I directed my mind to know, to investigate and to seek wisdom and an explanation, and to know the evil of folly and the foolishness of madness. (NASB ©1995)
