Ecclesiastes 5:9-11

New Catholic Bible

⁹ One who is covetous will never be satisfied with money,
    nor will the lover of wealth be content with gain.
    This too is vanity.
¹⁰ When riches increase,
    so do those who are eager to accumulate them,
and those who have accumulated them must remain content
    simply to feast their eyes on them.
¹¹ Sleep is sweet to the laborer,
    whether he has much or little to eat,
but the vast riches of a wealthy man
    do not allow him to sleep.
