Ecclesiastes 2:22-25

For what hath a man of all his labor, and of the striving of his heart, wherein he laboreth under the sun? For all his days are but sorrows, and his travail is grief; yea, even in the night his heart taketh no rest. This also is vanity. There is nothing better for a man than that he should eat and drink, and make his soul enjoy good in his labor. This also I saw, that it is from the hand of God. For who can eat, or who can have enjoyment, more than I?
