Ecclesiastes 2:24 (KJV)

For what hath man of all his labour, and of the vexation of his heart, wherein he hath laboured under the sun?

For all his days are sorrows, and his travail grief; yea, his heart taketh not rest in the night. This is also vanity.

There is nothing better for a man, than that he should eat and drink, and that he should make his soul enjoy good in his labour. This also I saw, that it was from the hand of God.

For who can eat, or who else can hasten hereunto, more than I?

For God giveth to a man that is good in his sight wisdom, and knowledge, and joy: but to the sinner he giveth travail, to gather and to heap up, that he may give to him that is good before God. This also is vanity and vexation of spirit.
