Ecclesiastes 2:23-26

²³For all his days are full of pains, and vexation is mingled with his employment: yea, even in the night his heart taketh not rest. Also this is vanity.

²⁴It is not a good thing inherent in man that he should eat and drink, and that he should make his soul enjoy happiness for his toil. Also this have I seen, that it cometh out of the hand of God.

²⁵For who can well eat, or who can enjoy earthly things more than I?

²⁶For to a man who is good in his presence God giveth wisdom, and knowledge, and joy; but to the sinner he giveth employment, to gather up and to bring together, that he may give it to him that is good before God. Also this is vanity and a torture of the spirit.
