Sirach 18:22-24

New Revised Standard Version, Anglicised Catholic Edition

²² Let nothing hinder you from paying a vow promptly,
    and do not wait until death to be released from it.
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.
