Wisdom of Ben Sira 11:18-20

New Catholic Bible

¹⁸ A man may become rich through caution and self-denial,
    and this is the reward he receives for it:
¹⁹ although he says, “Now I have found rest
    and I can live on my possessions,”
he does not know how long it will be
    before he must die and leave his possessions to others.
²⁰ Know your obligations and fulfill them;
    grow old at your work.
