Sirach 8:15-17

New Revised Standard Version, Anglicised Catholic Edition

¹⁵ Do not go travelling with the reckless,
    or they will be burdensome to you;
for they will act as they please,
    and through their folly you will perish with them.
¹⁶ Do not pick a fight with the quick-tempered,
    and do not journey with them through lonely country,
because bloodshed means nothing to them,
    and where no help is at hand they will strike you down.
¹⁷ Do not consult with fools,
    for they cannot keep a secret.
