Sirach 18:23-25

New Revised Standard Version Catholic Edition

²³ Before making a vow, prepare yourself;
    do not be like one who puts the Lord to the test.
²⁴ Think of his wrath on the day of death,
    and of the moment of vengeance when he turns away his face.
²⁵ In the time of plenty think of the time of hunger;
    in days of wealth think of poverty and need.
