Sirach 5:13-15

Revised Standard Version Catholic Edition

¹⁴ Do not be called a slanderer,
    and do not lie in ambush with your tongue;
for shame comes to the thief,
    and severe condemnation to the double-tongued.
¹⁵ In great and small matters do not act amiss,
    and do not become an enemy instead of a friend;
