Sirach 8:16-18

Revised Standard Version Catholic Edition

¹⁶ Do not fight with a wrathful man,
    and do not cross the wilderness with him;
because blood is as nothing in his sight,
    and where no help is at hand, he will strike you down.
¹⁷ Do not consult with a fool,
    for he will not be able to keep a secret.
¹⁸ In the presence of a stranger do nothing that is to be kept secret,
    for you do not know what he will divulge.^[a]
