Ecclesiastes 2:25

For all his days are sorrows, and his travail is grief; yes, even in the night his heart takes 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 to the man who pleases him, God gives wisdom, knowledge, and joy; but to the sinner he gives travail, to gather and to heap up, that he may give to him who pleases God. This also is vanity and a chasing after wind.
